Fof the reaction 2H2S(g)+O2(g)2S(s)+2H2O(l), which one of the following statements is absolutely true? The reaction is fourth order overall. The reaction is first order with respect to H2S and second order with respect to O2. The rate law cannot be determined from the information given. The rate law is: rate =k[H2S][O2]. The rate law is: rate =k[H2S2[O2]
