Question

Nitrogen reacts with oxygen according to the equation.
N_2(g) + O_2(g)   2NO_(g),∆H = +197KJ/mole
What is the effect of increase of the following on the position of the equilibrium?
Explain.

1. Pressure
2. Temperature

Answer 1

1. No effect
   The number of molecules on both sides of the reaction are the same/total volumes of reactants and products are equal.
2. Shifts to the right
   Forward reaction is favoured as an endothermic process will proceed.
