Use the information below to answer questions 1- 3. PCI,(g) 2 PCI;(g) + Cl2(8) PCI,(g) decomposes into PCI,(g) and Cl,(8) according to the equation above. A pure sample of PCI,(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCI5(g) is 1.00 atm. The temperature is held constant until the PCI,(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. PCI5 Potal = 1.00 atm PCI5, PCI3, and CI, Prstal = 1.40 atm Figure 1: Initial Figure 2: Equilibrium As the reaction progresses toward equilibrium, the rate of the forward reaction (A) increases until it becomes the same as the reverse reaction rate at equilibrium (B) stays constant before and after equilibrium is reached (C) decreases to become a constant nonzero rate at equilibrium (D) decreases to become zero at equilibrium If the decomposition reaction were to go to completion, the total pressure in the container would be (A) 1.4…
