The gas phase decomposition of (CH),0, (CH3)30 - CHACC) + Ma(o) + co(a), is studied at a certain temperature, giving the following data: Time (s) [(CH),0](M) 0.000 2.00+03 4.00+03 6.0 +03 8.0 +03 0.100 0.0254 0.00646 0.00164 0.000417 Figure out whether this reaction is first-order or second-order with respect to the concentration of (CH). Calculate the value of the rate constant. Pick the choice from below which gives the correct reaction order and value of the rate constant for this reaction. a) This reaction is first-order with the rate constant k = 1.370-035 b) This reaction is first-order with the rate constant 2.05e-035 c) This reaction is first-order with the rate constant k = 6.85e-043 d) This reaction is second-order with the rate constant k = 1.71-04 M11 De) This reaction is first-order with the rate constant k = 1.37e-04 5!
