1
Q
Define the rate of reaction
A
The rate of reaction is generally defined as the change in the concentration of reactants or products per unit time
2
Q
Relationship between rate of reaction and the gradient of a concentration time graph
A
Rate of reaction = |gradient of a concentration time graph|
3
Q
Units for rate of reaction
A
mol dm^-3 time^-1, where time can be s, min, hour etc
3
Q
3 methods to measure the rate of reaction
A
Measuring the time for a reaction to be completed, measuring the decrease in mass of a reactant i.e. rate of mass loss of reactant, measuring the rate of product (gas) formation
3
Q
Define initial rate of reaction
A
It refers to change in concentration of a reactant or product at t = 0
