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

Answer 1

Answer: (B)

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

$ln\frac{K_2}{K_1}=-\frac{\Delta H}{R}(\frac{1}{T_2}-\frac{1}{T_1})$
Hence Assertion is true.
$T_2>T_1$ and $\Delta H>0$ $\Rightarrow$ $K_2>K_1$

$\therefore$ Reason is also true.

But Reason doesn't explain Assertion

So option $B$ is correct.
