Statement 1: For an endothermic reaction, KP increases when the temperature is increased.

Statement 2: KP = KC(RT)Δ ng.

Options:

Answer:
B
Solution:

The van't Hoff equation gives ln(K2/K1) = (Δ H/R)[(T2 - T1)/(T1T2)] For Δ H > 0 and T2 > T1 the right side is positive, so KP increases and Statement 1 is correct

KP = KC(RT)Δ ng is a correct relation between the two constants

It does not say why heating an endothermic reaction raises K, so Statement 2 is not the explanation

Both are correct but II is not the explanation, option (b).
