12 Reaction Kinetics 12.1 Rate Law Rate of reaction is refered to as the change of the concentration of reactant or product with time. Consider the reaction A B The equation tells us that during the course of reaction, reactant molecules (A) are consumed while product molecules(B) are formed. As a result concentration of the reactant decreases while concentration of the product increases. Figure 12.1.1: The Change in Concentration with Time for the Reaction A B Instantaneous rate is determined from a graph of time versus concentration by drawing a line tangent to the curve at the point that corresponds to a particular time. Br 2 (aq) + HCOOH(aq) 2Br - (aq) + 2H + (aq) + CO 2 (g) The instantaneous rate of the above reaction at t = 100s, 200s and 300s are given by the slope of the tangents at these times in Figure 10.1.2.
