How does temperature affect the conditions when solving?

Temperature changes the equilibrium constant, so make sure you have the right K constant if looking at a chart that gives you multiple.

When temperature increases, it depends on whether your reaction is exothermic or endothermic. If the reaction is endothermic, requiring energy to proceed, then increasing temperature will create more product to use up the heat. Decreasing the temperature will create more reactant to regenerate the lost heat. If the reaction is exothermic, increasing the temperature will create more reactant to use up the heat, and decreasing the temperature will create more product to create more heat.

In essence, if the reaction is endothermic you can treat heat as a reactant, and if the reaction is exothermic, treat heat like a product.

Temperature also changes the equilibrium constant, equilibrium constants are usually standardized at 25 degrees Celsius. Unless the problem specifies otherwise, you can usually assume the reaction is room temperature (25C).

Depending on if the reaction is exothermic or endothermic, temperature will change the equilibrium constant (K) of the reaction. Usually, unless a problem says otherwise, we can treat the reaction like it is at room temperature.

Every K value correlates to a temperature. When you are given a table of k values, make sure you pick the one that correlates to the temperature you are given

Temperature is the only thing that affects the equilibrium constant, so it changes the value of k.

The equilibrium constant varies with changing temperatures.

When solving these kinds of problems, the temperature will most likely be a constant because changing the temperature during a reaction will change the equilibrium constant.

Temperature changes the equilibrium constant (K).

Temperature affects the equilibrium constant so if the reaction is exothermic (heat in the products) added heat will shift the reaction left and removing heat will shift the reaction right. On the other hand, if the reaction is endothermic (heat in reactants) added heat will shift the reaction right and removing heat will shift the reaction right.
