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

Answer

A

Explanation

`2.303` log `(K_(C_(2)))/(K_(C_(1)))` = `(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))`
