Explanation / Answer

PartA: On adding more CO , reaction rate will be increased .

The more reactant particles that collide per unit time, the more often a reaction between them can occur. Consequently, the reaction rate usually increases as the concentration of the reactants increases.

Part B: On raising temperature , reaction rate will be increased.

Increasing the temperature of a system increases the average kinetic energy of its constituent particles. As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate.

Part C:On removing catalyst the reaction rate will be decreased.

A catalyst is a substance that participates in a chemical reaction and increases the reaction rate without undergoing a net chemical change itself.

Part D:On removing O2,t he reaction rate will be decreased.

The less reactant particles that collide per unit time, the less often a reaction between them can occur. Consequently, the reaction rate decrases as the concentration of the reactants decreases.
