Question

Nitryl chloride, NO2CI, reacts with nitric oxide, NO. The forward reaction is exothermic.

NO2Cl(g) + NO(g) = NO2(g) + NOCl(g)

The reaction can reach equilibrium.

(a) What is meant by the term equilibrium for a reversible reaction?

(b) Explain why increasing the temperature increases the rate of reaction.

(c) State and explain the effect, if any, of increasing the temperature on the position of equilibrium

(d) State and explain the effect, if any, of decreasing the pressure on the position of equilibrium.

Answer 1

a) Equilibrium is the state of a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction.

b) Growing temperature increases the velocity of particles' movement and the amount of their effective collisions.

c) Increasing th temperature for the exothermic reaction will slow doun the rate of the forward reaction and speed up the rate of the reverse reaction.

d) Decreasing the pressure for this reaction will not effect the equilibrium.
