2. A catalyst is a substance that increases the rate of a chemical reaction but is not consumed by the reaction. A catalyst works by lowering the activation energy for a reaction, making it easier for reactants to form products. What effect, if any, would a catalyst have on a system already at equilibrium? Briefly explain.
A crystal of potassium permanganate was added to the hydrogen peroxide as a catalyst to speed up the decomposition of the hydrogen peroxide. Define a catalyst in simple terms and two provide two different example in which a catalyst is used to speed up a reaction.
