Interpretation:
Among the given reactions the reactants-favoured reactions has to be identified.
Concept Introduction:
Equilibrium constant: At equilibrium the ratio of products to reactants (each raised to the power corresponding to its
For a general reaction,
Equilibrium Constant & Direction of reaction:
Case 1:
Reaction is strongly product-favoured; equilibrium concentrations of products are much greater than equilibrium concentrations of reactants.
Case 2:
Reaction is strongly reactant-favoured; equilibrium concentrations of reactants are much greater than equilibrium concentrations of products.
Case 3:
Equilibrium mixture contains significant concentrations of reactants and products; calculations are needed to determine equilibrium concentrations.
