Question

Statement 1: The equilibrium constant may show higher or lower values with increase in temperature
Statement 2: The change depends on the heat of reaction at equilibrium.

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1 .
• B. Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1 .
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true.

Answer 1

Answer: (A)

$2.303 log \frac{K_{c_2}}{K_{c_1}}=\frac{\Delta H}{R}\frac{\left[T_{2}-T_{1}\right]}{T_{1}T_{2}};$
if $\Delta H=-ve, K_{c_2} < K_{c_1}$ if $\Delta H=+ve, K_{c_2} > K_{c_1}.$
