问答题 The following data were measured for the reduction of nitric oxide with hydrogen.
   2NO(g)+2H2(g)→N2(g)+2H2O(g). What is the rate equation for the reaction?
Initial concentration/(mol·dm-3) Initial rate of formation of H2O/(mol·dm-3·s-1)
c(NO) c(Hz)
0.10 0.10 1.23×10-3
0.10 0.20 2.46×10-3
0.20 0.10 4.92×10-3
【正确答案】设速率方程为V=k[C(NO)]m[c(H2)]n，
   根据第1，2组数据得出n=1；根据第1，3组数据得出m=2；
   故速率方程为v=k[c(NO)]2c(H2)，代入第1组数据1.23×10-3=k×0.102×0.10
   k=1.23，所以速率方程为v=1.23[c(NO)]2c(H2)
