WebHow does pH increase rate of reaction? Effect of pH on reaction rate. The structure of the enzyme has a great influence on the activity of the enzyme. In other words, changes in the structure of the enzyme affect the rate of chemical reactions. When the pH value of the reaction medium changes, the shape and structure of the enzyme will change. WebThere are five general properties that can affect the rate of a reaction: The concentration of the reactants. The more concentrated the faster the rate. Temperature. Usually reactions speed up with increasing temperature. Physical state of reactants. WebTemperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. has piers corbyn ever worked
