Question

The reaction quotient $\left(Q\right)$ for the reaction
$N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$
is given $Q=\frac{|N{H}_3{|}^2}{|N_2||H_2{|}^3}$
The reaction will produced from right to left if

• A. $Q=K_c$
• B. $Q<K_c$
• C. $Q>K_c$
• D. $Q=0$

Answer 1

Answer: (C)

$Q>K_c$

The reaction proceeds from right to left when $Q>K_c$ so that $O$ tends to decrease to become equal to $K_c$.
