At 903 k, the gas phase decomposition of ethane results in the following change in total pressure of a constant volume system: time s 0 120 240 360 480 600 720 total pressure 483 558 622 676 721 759 7912 show that the reaction is first order and evaluate the rate constant. (hint: you need to evaluate the actual partial pressure of c2ho during the reaction. look to the stoichiometry, think of pressure changes in this fixed volume system as reaction proceeds and hence work out a table of partial pressure values for c2h6, c2h4, and h2, then do the usual kinetic test for first order reactions! )
