2NO(g) ⇌ N2(g) + O2(g) + heat Stress: Increase pressure a) What is the resulting effect on the number of moles of O2 b) What is the resulting effect on the number of moles of NO

Question

2NO(g) ⇌ N2(g) + O2(g) + heat

Stress: Increase pressure

a) What is the resulting effect on the number of moles of O2

b) What is the resulting effect on the number of moles of NO

Answer 1

This is an exercise in understanding Le Chateliler's Principle. Read about it.

2NO(g) ⇌ N2(g) + O2(g) + heat

Increase pressure:

a). effect on moles of O2 gas is NO EFFECT. The reason is that there are 2 moles of gas on the reactant side and 2 moles of gas on the product side so increasing the pressure will have no effect.

b). effect on moles of NO is also NO EFFECT for the same reason given above.
