The half-life of a reaction is found to be inversely proportional to the cube of its initial concentration. The order of the reaction is:

Write the general reaction,its differential rate equation,and the rate law.

Which of the following determines the rate of a multistep reaction?

Which one of the following statements regarding the order of a reaction is not correct?

For the reaction $N_2O_5 \rightarrow 2NO_2 + \frac{1}{2} O_2$,given that:
$-\frac{d[N_2O_5]}{dt} = K_1[N_2O_5]$,
$\frac{d[NO_2]}{dt} = K_2[N_2O_5]$,
$\frac{d[O_2]}{dt} = K_3[N_2O_5]$
What is the relationship between $K_1$,$K_2$,and $K_3$?

For a reaction $A + B \rightarrow \text{Product}$,the order with respect to $A$ is $2$ and with respect to $B$ is $3$. If the concentration of both is doubled,by how much will the rate increase?
