CHEMISTRY 13.4: Effects of a Catalyst
Catalyst - answer a substance that increases the rate of a chemical reaction without
being consumed in the reaction
providing an easier route that has a lower activation energy - answerhow a catalyst
increases the rate of a chemical reaction
aids reactions that are already possible - answera catalyst cannot make an impossible
reaction possible, it only does this
homogeneous catalyst - answercatalysts that exist in the same phase as the reactants
heterogeneous catalyst - answercatalysts that are not in the same phase as the
reactants
surface catalysts - answerheterogeneous catalysts are often referred to as this for they
often absorb one or more reactants
enzymes - answergroup of proteins that serve as biological catalysts; found in living
cells and organs
inhibitors - answersubstances that slow the rate of a chemical reaction
