Question

Question 1. Phosphorous trichloride reacts with chlorine to produce phosphorus pentachloride: PC13(g) + Cl2(8) - PC1s(8) The equilibrium constant (Kc) for the reaction is 96 at 400 K If the equilibrium concentration of PC13 is 0.50 M and Cl, is 0.070 M, what is the equilibrium concentration of PCI ? Question 2. Consider the reaction between hydrogen and iodine H2(g) + 12(6) 2 HI(g) Kc = 64 Initially, a container was charged with 0.55 atm of H, and I2, what are the equilibrium partial pressures of all species?
