For the gas-phase reaction shown below, choose the answer which indicates how the rate of change of H2O is related to the rate of change of C3H6.
2 C3H6(g) + 9 O2(g) 6 CO2(g) + 6 H2O(g)
a) 6 [H2O] /t = - 2 [C3H6] /tb) 2 [H2O] /t = 6 [C3H6] /tc) 1/6 [H2O] /t = - 1/2 [C3H6] /td) - 1/6 [H2O] /t = - 1/2 [C3H6] /te) 1/2 [H2O] /t = - 1/6 [C3H6] /t
