Chapter 20, Problem 82IAE

Interpretation Introduction

Interpretation:

Time when total gas pressure in decomposition of $\text{di-}t\text{-butyl peroxide}$ becomes $2100\text{ mmHg}$.

Concept introduction:

Equilibrium constant $\left(K_{\text{c}}\right)$ can be defined as the ratio of the equilibrium concentration of products to the reactants with their stoichiometric coefficient given in the balanced chemical reaction as powers. Equilibrium constant $\left(K_{\text{p}}\right)$ is defined in terms of partial pressure of the gases present in the reaction. Hence, both of them are called as equilibrium constant. The only difference is that $K_{\text{c}}$ is defined as of molar concentration while $K_{\text{p}}$ is defined as of partial pressure of the gases.
