v Correct
Partial pressure is equal to the product of the total pressure and the mole fraction of a chemical species (Xi). Therefore, the partial pressures can be
compared based on changes to the number of moles. The stoichiometric relationship between N,H, and NH, is 1:2, so the rate at which the partial
pressure of NH, increases is twice the rate at which the partial pressure of N,H, decreases.
Part D
What is the rate of change of total pressure in the vessel during the reaction?

Consider the combustion of ethylene:
C2H (g) + 302(g)→2CO2(g) + 2H20(g)
If the concentration of C2H4 is decreasing at the rate of 3.8x10-2 M/s , what is the rate of change in the concentration of CO2?
Express the rate in molarity per second to two significant digits.
A[CO2]/At = 7.6×10-2 M/s

v Correct
The stoichiometric relationship between C2H4 and CO2 is 1:2, so the rate at which the concentration of CO2 increases is twice the rate at which C2H
decreases.
Part B
What is the rate of change in the concentration of H,O?
Express the rate in molarity per second to two significant digits.
A[H2O]/At = 7.6×10-2 M/s
