The equilibrium constant, K, for the following reaction is 1.29x10-2 at 600 K. ? COCI₂(g) CO(g) + Cl₂(g) An equilibrium mixture of the three gases in a 1.00 L flask at 600 K contains 0.302 M COCI2, 6.24x10-² M CO and 6.24x10-2 M CI₂. What will be the concentrations of the three gases once equilibrium has been reestablished, if 4.11x10-² mol of Cl₂(g) is added to the flask? [COCI₂] = 0.2457 = 0.0563 [CO] [Cl₂] = 0.0563 ΣΣΣ
The equilibrium constant, K, for the following reaction is 10.5 at 350 K. ? 2CH₂Cl₂(g) CH4(9) + CCl4(9) An equilibrium mixture of the three gases in a 1.00 L flask at 350 K contains 5.37x10-² M CH₂Cl₂, 0.174 M CH4 and 0.174 M CCI4. What will be the concentrations of the three gases once equilibrium has been reestablished, if 0.128 mol of CH4(9) is added to the flask? [CH₂Cl₂] = [CH4] = [CCI4] ΣΣΣ
