I need help with these problems.

For the following reaction, P(H2)/t was found to be 0.0574atm/s. N2(g)+3H2(g)2NH3(g) Determine P(NH3)/t for this reaction at the same time. 2. For the chemical reaction shown below, which of the following statements is reasonable? 2H2S(g)+O2(g)2S(s)+2H2O(1) a. The reaction is second order overall. b. The reaction is third order overall. c. The rate law cannot be determined from the information given. d. The rate law is, rate =k[H2S][O2]. e. The rate law is, rate =k[H2S]2[O2]
