Telangana Board Solutions for Chapter: Electrochemistry and Chemical Kinetics, Exercise 7: Intext Questions

For a reaction, $\mathrm{A}+\mathrm{B}\to$ Product; the rate law is given by, $\mathrm{r}=\mathrm{k}{\left[\mathrm{A}\right]}^{\frac{1}{2}}{\left[\mathrm{B}\right]}^2.$ What is the order of the reaction?

The conversion of molecules $\mathrm{X}$ to $\mathrm{Y}$ follows second order kinetics. If concentration of $\mathrm{X}$ is increased to three times how will it affect the rate of formation of $\mathrm{Y}$?
