Q
Initial rates table
A
- Using two experiments with only one change in reactants concentration. Order of a single reactant can be calculated by observing the change in rate
- May have to ‘create’ and experiment on a new row to be able to work out the orders
E.g double one reactant (with all others constant) that is first order, rate will double - To find k sub in values (from the first row of the table is easiest) into the overall rate equation
