PL Worksheet #7 17.5 Calculations in Equilibrium 1. Define the equilibrium equation (K) for the following reaction: Ni ( s ) + Cl 2 ( g ) NiCl 2 ( g ) K c = 1.55 * 10 −2 2. At equilibrium in the above reaction, are products or reactants favored? 3. Given 155 g of Ni, 0.250 M of Cl 2 and 0.155 M of NiCl 2 , solve for Q and determine which direction the reaction will proceed. 4. Create an equilibrium table using the initial concentrations in question 3. 5. Solve for the equilibrium concentrations of each gaseous chemical species in this reaction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
