Consider the combustion of ethylene, C2H4+3O2=2CO2+2H2O. If the conentration of C2H4 is decreasing at the rate of 0.036M/s, what are (A)the rates of change in concentrations of CO2 B)rate of change of H2O concentration? (2)the rate of decrease in N2H4 +H2=2NH3 is 74 torr per hour. What are a)rate of change of NH3 partial pressure? b)rate of change of NH3 total pressure
