Chapter 15, Problem 78E

Interpretation Introduction

Interpretation: The reaction which will occur at the larger rate at room temperature needs to be determined and the reason for same should be explained.

  ${\text{2Ce}}^{\text{4+}}{}_{\text{(aq) }}{\text{+ Hg}}_2^{2+}{}_{\text{(aq) }}\stackrel{}{\to }{\text{2Ce}}^{3+}{}_{\text{(l)}}+2{\text{Hg}}_{}^{2+}{}_{\text{(aq) }}$

  ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}{}_{\text{(aq) }}{\text{+ OH}}^{\text{-}}{}_{\text{(aq) }}\stackrel{}{\to }{\text{2H}}_{\text{2}}{\text{O}}_{\text{(l)}}$

Concept Introduction:

Chemical kinetic is the branch of chemistry that deals with kinetic or rate of a chemical reaction. The rate of reaction can be defined as the change in the concentration of reactant and product with time. The rate of reaction mainly depends on the activation energy. The activation energy is the energy that is minimum energy needed for reactant molecule to convert into products.
