IB Chemistry: Rates of reaction answers

1. The rate of reaction is the change in the concentration of one of the products or of one of the reactants divided by time.2. The rate of the reaction depends upon the concentration of the reactants. As the reaction proceeds the concentration of the reactants decreases so there are less particles present to react.3.(a) By taking the gradient at time t = 1.5 minutes the rate = 26.5 / 2.45 = 10.8 cm3 min-1
