Unformatted text preview: If you change the concentration and… Example Order Nothing happens to the rate Concentration 2x, rate remains the same 0 The rate changes by the same amount Concentration 2x, rate increases by 2x 1 The rate changes by x 2 Concentration 3x, rate increases by 9x 2 rate = k [F 2 ] a [ClO] b a = 1 and b = 1 overall order = 1 + 1 = 2 rate = k [F 2 ] [ClO] What is the value of k? rate = k [F 2 ] [ClO] 0.0012 = k [0.10] [0.010] k = 1.2 1 M1 s1 What would the rate be if… [F 2 ] = 0.30 M, [ClO] = 0.030 M rate = k [F 2 ] [ClO] Rate = 1.2 [0.30] [0.030] Rate = 0.0108 M/s Conclusions: Rate laws are based on the concentration of the reactants Write the general rate equation for a reaction first Use data to determine the order of the reaction, the value of k (rate constant), and to predict what the rate of the reaction would be at other concentrations...
