The reversible chemical process to form phosphorous pentachloride, PCI,(g), is carried out and the concentrations of the starting substances and products are carefully monitored. Which of the following is true at 200 seconds? Cl₂(g) + PCI3(g) → PCI5(g) Time (s) [Cl₂] mol/L [PCI3] mol/L [PCI5] mol/L 0 2.00 2.00 0.00 40 1.80 1.80 0.20 80 1.60 1.60 0.40 120 1.50 1.50 0.50 160 1.42 1.42 0.58 200 1.42 1.42 0.58 240 1.42 1.42 0.58 The rate of the forward process is greater than the rate of the reverse process. The rate of the reverse process is zero. The rate of the forward process is equal to the rate of the reverse process. The rate of the forward process is less than the rate of the reverse process.
