Question

Explain the effect of (i) increase in pressure and
(ii) increase in temperature on the following
reaction :
N2(g) + 3 H2(g) ⇌ 2 NH3(g), ΔrH° = - 92.2 kJ mol-1

Answer 1

According to the Le Chatelier's principle

1. Pressure increase will cause shift of balance towards products

2. Temperature increase will cause shift of balance towards substrate
