What is the effect of a catalyst on the equilibrium constant of a reaction?
Step 1: Understand what a catalyst is. A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.
Step 2: Learn about equilibrium in a chemical reaction. Equilibrium is the point where the forward and reverse reactions occur at the same rate, so the concentrations of reactants and products remain constant.
Step 3: Know what the equilibrium constant (K) is. The equilibrium constant is a number that expresses the ratio of the concentrations of products to reactants at equilibrium.
Step 4: Recognize that a catalyst affects the speed of the reaction but not the position of equilibrium. It helps the reaction reach equilibrium faster but does not change the concentrations of reactants and products at equilibrium.
Step 5: Conclude that since the concentrations at equilibrium do not change, the equilibrium constant (K) remains the same when a catalyst is added.
