why does the temperature change k?

From a kinetics standpoint, temperature changes K because temperature affects the forward and reverse rates of the reaction. This is because K=k/k’ where lowercase k is a rate constant. When the temperature is changed, the rate constant is affected. Therefore, K changes with temperature.

specifically, if temperature increases, then so does the rate constant. If temperature decreases, the rate constant decreases as well. In short, there is a direct relationship between temperature and the rate constant.

Temperature affects the forward and reverse reaction rates, which subsequently affects the rate constant (for K=k/k’ and k = rate constant). So when temperature changes, the rate constant, (and K) also changes.

K is temperature dependent. If temperature changes, the rate of the reaction changes which affects K.
