Where d H 2 dt is the slope for the curve of concentration of H 2 versus time at time t. No matter which quantity is measured during the course of a reaction. The change in volume of a reactant or product can be followed during a reaction.
Identify the correct equation to calculate the rate of reaction.
We calculate the average rate of a reaction over a time interval by dividing the change in concentration over that time period by the time interval. A way to determine the average rate of a reaction is by using data plotted on a graph. Average rate of a reaction is defined as the rate of change of concentration per unit time. It is calculated by dividing the total change in concentration of any one of the reactant or product by the total time taken to do so.
