Consider the following equilibrium reaction at a given temperature: A (aq) + 3 B (aq) ⇌ C (aq) + 2 D (aq) Kc = 178. If initially the concentrations of the chemical species are as follows: [A]o = 0.364 M [B]o = 0.170 M [C]o = 0.132 M [D]o = 0.932 M to which direction will the reaction run to reach equilibrium?

The reaction proceed toward product side or in forward direction.

Explanation:

is the constant of a certain reaction at equilibrium while is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

The expression of for above equation follows:

We are given:

Putting values in above equation, we get:

We are given:

There are 3 conditions:

As, , the reaction will be favoring product side.

Hence, the reaction proceed toward product side or in forward direction.
