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

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

A

Explanation

`2.303 log (K_(c2))/(K_(c1)) =(Delta H)/(R) [T_(2) - T_(1))/(T_(1)T_(2))` ,
if `Delta H = -ve`, `K_(c_(2)) lt K_(C_(1))` if `Delta H = +ve`, `K_(C_(2)) gt K_(C_(1)` .
