Suppose "2.83 g" of ammonium chloride solid is placed into a closed, evacuated rigid container, and allowed to decompose at a certain temperature. If 40% of it decomposed into ammonia and hydrogen chloride gas, what is K_c for this reaction?
1 Answer
The equilibrium constant,
Explanation:
The first step in any equilibrium problem like this is to write the complete balanced equation:
The form of
The
The starting amount of reactant is
Because 40% of the reactant decomposed, the equilibrium concentrations are:
The value of
