Question

Consider this equilibrium:

Answer 1

Answer:

It decreases as the concentration of products decreases.

It increases as the concentration of products increases.

Explanation:

the equilibrium reaction is

$N_{2}(g)+O_{2}(g)2NO(g)$

As per equilibrium,

a) there will be no effect of pressure change on the equilibrium as the number of gaseous molecules are same on both the side of reaction.

b) there will be no effect of addition of inert gas on the equilibrium as the number of gaseous molecules are same on both the side of reaction.

c) the reverse reaction rate can be increased by

i) decreasing the concentration of reactants

ii) increasing the concentration of products

Answer 2

It is C). It decreases as the concentration of products increases.
