What will happen to the rate if the concentration of A is doubled and the concentration of B is tripled?
The rate increases 8 times of original value.
What will happen to the reaction rate if the concentration of A is tripled?
In a third order reaction with two reactants, if you triple the concentration of one of the reactants, the rate increases by a factor of 3.
When chemical RXN takes place during the course of RXN the rate of RXN?
Rate of reaction remains constant during the complete reaction.
What is change in rate if concentrations of both reactants are doubled?
If concentrations of both the reactants A and B are doubled, the rate increases by a factor of 8, so. R”=k[2A]x[2B]y=8R…( iii)
What happens to the rate if the concentration of A is halved?
If you halve the concentration, you halve the rate, and so on. The rate is proportional to the square of the concentration. If you double the concentration, you multiply the rate by four.
What happens when you double the concentration of a second order reaction?
where k is a second order rate constant with units of M-1 min-1 or M-1 s-1. Therefore, doubling the concentration of reactant A will quadruple the rate of the reaction.
How do you find M and N in rate law?
If m is 2, the reaction is second order with respect to A. If n is 1, the reaction is first order in B. If n is 2, the reaction is second order in B. If m or n is zero, the reaction is zero order in A or B, respectively, and the rate of the reaction is not affected by the concentration of that reactant.
When a chemical reaction takes place during the course of?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
For which of the following the unit of rate constant and rate of the reaction are same?
If the value of n is 0, it will be zero order reaction and if it is 1 then it first order reaction and so on. Therefore, in the zero-order reaction, the rate is independent of the concentration of reactants and hence, the units of rate and rate constant becomes equal which is mol/L/time.
What is the order of the reaction in a B and overall?
The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2.
What happens when the concentration of a reactant is doubled?
Therefore rate of a reaction doubles when concentration of a reactant of a first order reaction doubles. In the reaction A+B–>C, if the concentration of A is tripled and B is doubled, then what is the rate? For the reaction A+B→C, the reaction is likely to be second order, first order in each reactant (A or B).
What is the Order of the Reaction 2a + B2C?
For a reaction 2A + B 2C, with the rate equation: Rate = k[A]2[B] (a) the order with respect to A is 1 and the order overall is 1. (b) the order with respect to A is 2 and the order overall is 2. (c) the order with respect to A is 2 and the order overall is 3. (d) the order with respect to B is 2 and the order overall is 2.
What are the conditions for a reaction to be favored kinetically?
(a) If reaction A is exothermic and reaction B is endothermic then reaction A is favored kinetically. (b) At the same temperature the rate of reaction B is greater than the rate of reaction A. (c) The energy of reaction A must be greater than the energy of reaction B.
What is the activation energy of the reverse reaction?
(1) The reverse reaction has an activation energy equal to 50 kJ/mol. (2) The reverse reaction has an activation energy less than 50 kJ/mol. (3) The reverse reaction has an activation energy greater than 50 kJ/mol. (4) The change in internal energy is less than zero. (5) The change in internal energy is greater than zero.
