MISSED THIS? Watch KCV: Finding Equilibrium Concentrations from Initial Concentrations Calculate the equilibrium partial pressure of BrCl. IWE: Finding Equilibrium Concentrations from Initial Express your answer in torr to three significant figures. Concentrations in Cases with a Small Equilibrium Constant ; Read Section 16.8. You can click on the Review link to access the section in your eText. Consider the reaction Br2(g)+Cl2(g)2BrCl(g)Kp=1.11104at150K A reaction mixture initially has a Br2 partial pressure of 751 torr and a Cl2 partial pressure of 697 torr at 150K.
