Chemical Reaction Shift

Postby Abby Ellstrom 1I » Tue Nov 28, 2017 10:17 pm

Since the equilibrium constant does not change, when a question asks which way the reaction shifts, is that referring to the value of Q?

The shifting to the right or left still refers to the equilibrium constant. The reaction shifts to the right if K is greater than 1 x 10^3 and the reaction shifts to the left if K is less than 1 x 10^-3. A large K means that there are more products than reactants at equilibrium, which is why the reaction shifts to the right.
