2. The decomposition of methanol was measured at 1200 K. Determine the reaction order and rate constant. (You can work in either pressure or concentration.) CH2OH(g) H2(g) + H2CO(g) Time /s PChoh /bar 0.0 0.997 30.0 0.520 60.0 0.286 90.0 0.148 120.0 0.080 150.0 0.043 (Answer: first order; k = 0.020 s)
