Kinetics extra practice problems general types groups of problems rates of change in chemical reactions p1 first order rate law calculations p9 the look of concentration time graphs p2 reaction energy diagrams activation energy transition states p10 rates average rates determination of rates from. Kinetics practice problems and solutions determining rate law from initial rates use the ratio of initial rates to get the orders 2 consider the table of initial rates for the reaction 2clo. Chemical reaction rates measure the change in concentration of the substance per unit time the coefficient of the chemical equation shows the whole number ratio of materials needed or products produced by the reaction this means they also show the relative reaction rates step 1 find b rate b rate a b coefficient of a b coefficient of a x rate b rate a b 2 x 0150 0050 b 2 x 3 b . Kinetics practice problems ex 1 consider the following reaction nh 4 aq no 2 given the relative activation energies for the forward and reverse reactions the rate for the forward reaction should be greater than the rate for the reverse reaction a lower e
