Embibe Experts Solutions for Chapter: Chemical Kinetics, Exercise 1: Exercise 1

Which of the following expressions is correct for the rate of reaction given below? $5{\mathrm{Br}}^{-}\left(\mathrm{aq}\right)+{\mathrm{BrO}}_3^{-}\left(\mathrm{aq}\right)+6{\mathrm{H}}^{+}\left(\mathrm{aq}\right)⟶3{\mathrm{Br}}_2\left(\mathrm{aq}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

A catalyst increases the rate of reaction by:

For the reaction ${\mathrm{H}}_2+{\mathrm{Br}}_2\to 2\mathrm{HBr}$, the overall order is found to be $3/2$. The rate of the reaction can be expressed as:

For a first order reaction, the plot of $\text{'}\mathrm{t}\text{'}$ against $\log \mathrm{C}$ gives a straight line with slope equal to:

In a certain reaction, $10\%$ of the reactant decomposes in one hour, $20\%$ in two hours, $30\%$ in three hours, and so on. The dimension of the rate constant is:

The data for the reaction $\mathrm{A}+\mathrm{B}\to \mathrm{C}$ is

A large increase in the rate of a reaction, for a rise in temperature, is due to

For the reaction, ${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{Br}}_2\left(\mathrm{g}\right)\to 2\mathrm{HBr}\left(\mathrm{g}\right)$, the experiment data suggested that $\mathrm{r}=\mathrm{k}\left[{\mathrm{H}}_2\right]{\left[{\mathrm{Br}}_2\right]}^{1/2}$. The molecularity and order of the reaction are, respectively:
