Q. 'A' decomposes to give 'X' by a first order process with a rate constant of $6.93\times {10}^{-2}mi{n}^{-1}$. The reactant 'A' in the presence of a catalyst gives 'Y' via a second order mechanism that has a rate constant of $0.2M^{-1}mi{n}^{-1}$. If both the half-lives are the same, what would the initial concentration of A be?

Q.

In a reaction, $A+B\to$ Product, rate is doubled when the concentration of B is doubled and rate increases by a factor of 8 when the concentrations of both the reactants (A and B) are doubled. Rate law for the reaction can be written as :

1. Rate $=k\left[A\right][B{]}^2$

2. Rate $=k\left[A{]}^2\right[B{]}^2$

3. Rate $=k\left[A\right]\left[B\right]$

4. Rate $=k\left[A{]}^2\right[B]$
