When concentration of reactant in reaction A B is increased by 8 times the rate increases only 2 times the order of the reaction would be?

Posted on August 22, 2022 by Author

When concentration of reactant in reaction A B is increased by 8 times the rate increases only 2 times the order of the reaction would be?

1/n.
When the concentration of a reactant in reaction A→B is increased by 8 times but rate increases only 2 times, the order of the reaction would be 1/n.

What happens to the rate of a reaction when the concentration of the reactants is increased?

Reactant Concentrations Raising the concentrations of reactants makes the reaction happen at a faster rate. With an increase in concentration, the number of molecules with the minimum required energy will increase, and therefore the rate of the reaction will increase.

When the concentration of A in the reaction a B gives AB is doubled the rate of reaction will be?

If concentration of B is doubled, the rate becomes four times.

What will happen to the rate of reaction if the concentration of A is doubled?

When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When you double the concentration the rate goes up four times.

What is the half life period of first order reaction?

The half life period of a first order reaction is 20 minutes.

When the initial concentration of the reactant is doubled?

When the initial concentration of the reaction is doubled, the half – life is also doubled.

Why does increasing the concentration increase rate of reaction?

How does concentration affect the rate of a reaction? Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. By increasing the pressure, you squeeze the molecules together so you will increase the frequency of collisions between them.

Why does increasing the concentration of reactants increase the reaction rate apex?

When more particles are present in a given amount of space, a greater number of collisions will naturally occur between those particles. Since the rate of a reaction is dependent on the number of collisions occurring between reactants, the rate increases as the concentration increases.

How is the rate of reaction affected if the concentration of B is quadrupled?

The k is the rate constant which varies reaction to reaction so for this reaction its value will be different. It is clearly visible that the rate is increased four times when the concentration of B is doubled. Therefore, the overall order of the reaction will be 2.

When the concentration of A is doubled the rate increases by a factor of?

10
First-Order Reactions If the concentration of A is doubled, the reaction rate doubles; if the concentration of A is increased by a factor of 10, the reaction rate increases by a factor of 10, and so forth.

Why does a higher concentration increase the rate of reaction?

If the concentration of reactants is increased, there are more reactant particles moving together. There will be more collisions and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction will be.

How do the results show that increasing the concentration of acid increases the rate of reaction?

As you can see, the greater the concentration of the acid used in a reaction the steeper the curve and the shorter the reaction time. Hence, these results show that an increase in concentration increases the rate of a reaction. At low temperatures the reacting particles have less energy.

When the concentration of reactant is increased eightfold the rate increases?

When the concentration of reactant in reaction A—->B is increased eightfold, the rate increases only twofold. What would be the order of reaction? – Quora When the concentration of reactant in reaction A—->B is increased eightfold, the rate increases only twofold.

What happens when the concentration of the reactant is doubled?

doubled, the reaction is the first-order. If the rate becomes 4-fold times (quadruples) when the concentration of the reactant is doubled, the reaction is the second-order and. similarly, the third, the fourth, and the higher orders.

How do you calculate the rate of reaction from concentration?

We know, Rate of reaction is directly proportional to the concentration of the reactant raised to its order. where k is the rate constant, [A] is the concentration and n is the order of the reaction. Given, New rate = 2 * Old rate, new concentration = 4 * old concentration.

When is there a limit to the rate of reaction?

This is especially true when concentrations are low and few molecules or ions are reacting. When concentrations are already high, a limit is often reached where increasing the concentration has little effect on the rate of reaction.
