Assertion : For a gaseous reaction,

x A+y B \rightleftharpoons l C+m D, K_p=K_C .

Reason : Concentration of gaseous reactant is taken to be unity.

View answer and explanation

Correct option: D

If the assertion and reason both are false.

Option D (If the assertion and reason both are false) is correct. The assertion is false because

K_p = K_c

only when

\Delta n_g = 0

, and the reason is false because the concentration of gaseous reactant is not always unity.
