Mass of Product (y) vs Time (x) graph and Concentration of Reactant (y) vs Time (x) graph are two graphs which could be used to work out the rate of reaction from the gradient.
What is Rate of reaction ?
It is reffered as the speed at which a chemical reaction proceeds.
It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
The rates of two or more reactions can be compared using a graph of mass or volume of product formed against time.
concentration of reactant against time of reaction is used to find the instantaneous rate of reaction at a given time.
