Equilibrium Ques 20
20. For a given exothermic reaction, $K_p$ and $K_P^{\prime}$ are the equilibrium constants at temperatures $T_1$ and $T_2$, respectively. Assuming that heat of reaction is constant in temperature range between $T_1$ and $T_2$, it is readily observed that:
[2014]
(a) $K_p>K_P^{\prime}$
(b) $K_p<K_P^{\prime}$
(c) $K_p=K_P^{\prime}$
(d) $K_p=\frac{1}{K_p^{\prime}}$
Show Answer
Solution:
- (a) In exothermic reactions on increasing temperature value of $K_p$ decreases
$\therefore K_p>K_p{ }^{\prime} \quad$ (Assuming $T_1<T_2$ )
