Question

4NH3(g) + 5O2(g) ⇌ 4NO(g) + 6H2O(g)

reaction will get affected by increase of pressure? Also mention, whether change will cause the reaction to go into forward or backward direction?

Answer 1

Δn = (4 + 6) - (4 + 8) = +1

The reaction proceeds with an increase in the number of ***** of the gaseous components and hence in the volume of the system.

Therefore, an increase in pressure will vapour the backward reaction, i.e., the reaction will move towards left (reactants side).
