Answer 1

1. Given the following equation: N2 (g) + 3 H2 (g) ↔ 2NH3 (g) ΔH = -92 kJ/mol

a. this reaction is exothermic as ΔH is -ve

b. the equilibrium will shift 2 the left if nitrogen gas is removed

c. the equilibrium shift 2 the right if the temperature is lowered

d. the equilibrium shift 2 the left if ammonia (NH3) is added

e. principle of thermodynamic potential or Gibbs energy is used to answer B-D

Answer 2

e. I will answer the last one first - the equation describes a reversible reaction and the equilibrium is determined by the Le Châtelier's principle.

a. It is exothermic.

b. It will shift towards the reactants side (N2+H2).

c. It will shift towards the product side (NH3).

d.  It will shift towards the reactants side (N2+H2).
