WebThe reaction rate can depend on how concentrated our reactants are. A chemical reaction’s rate law is an equation that describes the relationship between the concentrations of reactants in the reaction and the reaction rate. In the standard form, the rate law equation is written as: R = k [A] n [B] m. WebIn this case, you can still calculate the rate of reaction by using the following (slightly different) formula: Rate = 1 ÷ Time. ... Calculate the rate of reaction at pH 6. Step One: Write out the equation for calculating the rate of enzyme activity. Rate = 1 ÷ Time. Step Two: Substitute in the known values and calculate the rate. Rate = 1 ÷ ...
