Question

Which one of the following statements is not correct? [2017]
(a) The value of equilibrium constant is changed in the
presence of a catalyst in the reaction at equilibrium
(b) Enzymes catalyse mainly bio-chemical reactions
(c) Coenzymes increase the catalytic activity of enzyme
(d) Catalyst does not initiate any reaction

Answer 1

The value of equilibrium constant is changed in the  presence of a catalyst in the reaction at equilibrium is the incorrect statement.

Explanation:

• A catalyst deceases activation energies both the backward and forward reactions by the equal number and speeds up the backward and forward and reaction by the equal rate. The equilibrium constant is therefore not affected by the catalyst at a given temperature. The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium.
• Enzymes are biological catalysts (bio catalysts) and proteins. This accelerate chemical reactions.
• Inorganic substrates are co-factors. The co-factors need to make a chemical reaction to the substrate and enzyme, the rate catalysis will raise for others.
