K value at a specific temp
In the “skills you have mastered” section of 5J, it says we should be able to predict the value of K at one temperature from its value at another temperature. Lavelle excluded part of this section from the assigned reading, but I just wanted to make sure. Should we be able to do this? Have we addressed it at all in lecture?

We talk about activities when we talk about K. When we use partial pressures and concentrations to calculate K, we're actually using approximations. In reality, K is calculated by using activities.

Re: K value at a specific temp
When the temperature is increased, K is higher. When the temperature is decreased, K is lower.

Re: K value at a specific temp
Depending on the type of reaction (endothermic or exothermic), temperature affects K differently, increasing it for endothermic ones and decreasing it for exothermic ones.

Re: K value at a specific temp
we only have to predict the K value at a temperature change for exo/endothermic reactions. That's all that was covered in lecture
