Reaction Rates
- The rate of reaction measures the speed of a reaction or how fast it is.
Rate of reaction= amount of reactant used/time
OR
amount of product formed/time
- An average rate of reaction can be found by measuring the time it takes for a certain amount of solid to appear in a solution.
- If a gas is given off in the reaction, its average rate can be found by measuring the time taken to collect a certain amount of gas.
The rate of a reaction at any given time can be found from the Gradient, or slope of the line on a graph of amount of reactant or product against time. The steeper the gradient is, the faster the reaction is at that time.
