Question

Assertion: Effect of temperature on $K_{c}$ and $K_{p}$ depends on enthalpy change.
Reason: Increase in temperature shifts the equilibrium position to the product side in endothermic direction.

A

The Assertion is True, Reason is True, Reason is a correct explanation of Assertion

B

The Assertion is True, Reason is True, Reason is not a correct explanation of Assertion

C

The Assertion is true, Reason is False

D

The Assertion is False, Reason is True

Solution

Verified by Toppr

Correct option is B)

$l n \frac{K _{2}}{K _{1}} = - \frac{Δ H}{R} (\frac{1}{T _{2}} - \frac{1}{T _{1}})$
Hence Assertion is true.

$T_{2} > T_{1}$ and $Δ H > 0$ $\Rightarrow$ $K_{2} > K_{1}$
$∴$ Reason is also true.
But Reason doesn't explain Assertion
So option $B$ is correct.
