Concentration of enzyme: rate of reaction increases as concentration of enzyme increases. pH: extremes of pH denature enzymes. Surface area: rate of reaction increases as surface area increases. Inhibitors: if there are any impurities, then they will restrict the rate of the reaction. Key Factor: I will be using temperature as a variable, and keeping all other factors constant.
