A. Consider the combustion of ethylene, C2H4 (g) + 3O2 (g) --> 2CO2 (g) + 2H2O (g). If the concentration of C2H4 is decreasing at the rate of 0.23 M/s, what are the rates of change in the concentration of CO2 and H2O?
B. The rate of decrease in N2H4 partial pressure in a closed reaction vessel from the reaction N2H4 (g) + H2 (g) --> 2NH3 (g) is 45 torr/hr. What are the rates of change of NH3 partial pressure and total pressure in the vessel?

A. Since the stoichiometry of both products is 2 mols/1 mol C2H4, their concentrations will be INCREASING at a rate of 0.46 M/s.
B. To get these answers, first determine the stoichiometries for each compound, and then consider whether the compound's concentration is increasing or decreasing...

reaction fee shows the fee that reactants bypass to products and reaction time shows the time it takes. reaction time and reaction fee are inversely proportional, and whilst the fee will boost, the time decreases.
