Consider the combustion of ethylene: C2H4(g)+3O2(g)→2CO2(g)+2H2O(g)C2H4(g)+3O2(g)→2CO2(g)+2H2O(g) Part A: If the concentration of C2H4C2H4 is decreasing at the rate of 3.8×10−2 M/sM/s , what is the rate of change in the concentration of CO2CO2? Express the rate in molarity per second to two significant digits Part B: What is the rate of change in the concentration of H2OH2O? Express the rate in molarity per second to two significant digits. Part C: Consider the following reaction: N2H4(g)+H2(g)→2NH3(g)N2H4(g)+H2(g)→2NH3(g) If the rate of decrease for the partial pressure of N2H4N2H4 in a closed reaction vessel is 76 torr/h, what is the rate of change for the partial pressure of NH3NH3 in the same vessel? Express the rate in torrs per hour to two significant digits. Part D: What is the rate of change of total pressure in the vessel during the reaction? Express the rate in torrs per hour to two significant digits.
