Question

We know that the relationship between $K_c$ and $K_p$ is $K_p = K_c(RT)^{\Delta n}$ What would be the value of $\Delta n$ for the reaction? $NH_4Cl(s) \rightleftharpoons NH_3(g) + HI(g)$
(a) 1
(b) 0.5
(c) 1.5
(d) 2

Answer 1

The question is wrong product should be HCl not HI

Answer : 1

Explanation : delta n = moles of product - moles of reactants

delta n = 1+1-1 = 1
