H2O2(aq)H2O(I)+1/2O2(g) Hint: It is not necessary to graph these data. (1) The half life observed for this reaction is (2) Based on these data, the rate constant for this order reaction is min1. NH31/2N2+3/2H2 the following data were obtained: Hint: It is not necessary to graph these data. (1) The observed half life for this reaction when the starting concentration is 3.69103M is s and when the starting concentration is 1.85103M is s. (2) The average rate of disappearance of NH3 from t=0s to t=997s is Ms1 (3) The average rate of disappearance of NH3 from t=997s to t=1.50103s is Ms1 (4) Based on these data, the rate constant for this order reaction is Ms1.

In a study of the gas phase decomposition of hydrogen iodide at 700K HI(g)1/2H2(g)+1/2I2(g) the following data were obtained: Hint: It is not necessary to graph these data. (1) The observed half life for this reaction when the starting concentration is 1.2M is 5 and when the starting concentration is 0.610M is 5. (2) The average (1/[ HI ])/t from t=0s to t=828s is M1s1 The average (1/[HI])/t from t=828s to t=2.48103s is M1s1. (3) Based on these data, the rate constant for this order reaction is M1s1
