The

Answer 1

change in amount / time

Question 2

During a reaction, the reactants are used up and changed into products

This means that as the reaction proceeds, the concentration of the reactants is ………….. and the concentration of the products is ……………

Answer 2

decreasing

increasing

Question 3

Because of this, the rate of the reaction is not the same throughout the reaction but changes
The rate of reaction during the reaction can be calculated from a

Answer 3
