the equilibrium changes in responds to change in temperature

K also correlates to cell potential too. If the cell potential is large and positive, then delta G would be a large negative. Since delta G is also equal to -RTlnK, K would also be a large number.

K can be affected by cell potential. Cell potential depends on factors such as concentration, gas pressure, and temperature so all of these factors also affect K.

if you are referring to the reaction rate constant (lowercase k), then I believe that varying the temperature and solvent would affect its value.

An increase in temperature causes an increase in the rate constant (k) and a decrease in temperature causes a decrease in the rate constant (k).

A higher concentration of initial reactant usually indicates higher k as well.

Factors that can affect k include cell potential and temperature.

When asked about k and what can change k, you should know that temperature affects k. This makes sense, because if something were to get hotter, the reaction will go faster (k will increase). The opposite goes for when something gets colder.
