COMEDK Exam 2016 Solved Paper

For the following reaction,
N2+3H2⇌2NH3+92.3‌kJ
(i) Reducing temperature is favourable as it is an exothermic process and shift equilibrium towards right.
(ii) Also on removing NH3 equilibrium shift towards right according to Le-Chatelier's principle.
(iii) ∆ng is negative for the process. Increase in pressure, equilibrium towards right.
For an exothermic reaction, increasing temperature shifts the reaction to reactant side.
