Question

For the reaction PCI₅ (g) ⇌ PCI₃ (g) + Cl₂ (g) Kc = 0.0454 at 261°C. If a vessel is filled with these gases such that the initial concentrations are [PCI₅ ] = 0.25M, (PCI;] = 0.20 M, and [Cl₂ ] = 2.25 M, in which direction will a reaction occur and why? A) toward products because Q = 0.56 B) toward reactants because Q = 1.8 C) it is at equilibrium D) toward reactants because Q = 0.0454 E) toward products because Q = 0.022

00:01 Alright, so we know some concentrations of the species in this system in this gas phase reaction and we want to determine what direction the reaction is going to proceed in to reach equilibrium.
00:11 The kc value is given as 0 .0454.
00:16 So we can calculate the value of the reaction quotient under the given concentrations and compare that to the value of k.
00:22 So it's equal to the product concentrations over the reacting concentrations, each of them raised to their coefficients, but we have coefficients of 1 so we don't need to worry about that.
00:35 So pcl3 was 0 .20 molar, cl2 is 2 .25 molar, and pcl5 is 0 .25 molar...
