General Chemistry II Laboratory Manual, 2017 Revision Questions: 1) Using the equilibrium shown below, fill in the table showing which way each stress would shift things to reestablish equilibrium and the effect on the value of Kc cach stress will have. Assume that only the stress that is being applied is happening to the system at equilibrium and nothing else changes (e. the volume of the container remains constant unless you are told otherwise). 2CHCl(g) +Cl2(g) = 2CCL.(1)...
