Step One: Write out the equation for calculating the rate of enzyme activity. Rate = Change ÷ Time. (In this case, Rate = Amount of substrate used ÷ Time) Step Two: Substitute in the known values and calculate the rate. Rate = 15 g ÷ 2 hours. Rate = 7.5 g / hr or 7.5 g hr⁻¹ in which soil horizon is humus found

"WebSo this question gives us a table and wants us to find the order of the reaction and then the rate law and the value of the rate constant K. And so we know that the reaction is first order. And the reason we know that its first order is because when you double the concentration, you double the rate which defines the first order reaction. " - How is rate of reaction measured
