a. explain why this is.
b. will the addition of a catalyst alter the value of delta "G" for the reaction? explain.
---
i'm not sure for an answer for A, but i think b will be a yes because a catalyst lowers activation energy and will take less time for a reaction to occur. help plz?
thanks!

b. catalys lowers activation energy. your added statement does not have anything to do with deltaG
b. The addition of a catalyst does not alter the value of delta "G" for the reaction. The role of a catalyst is to lower the activation energy required for the reaction to proceed, but it does not change the difference in free energy between reactants and products, which is represented by delta "G". By providing an alternative reaction pathway with a lower activation energy, a catalyst enables the reaction to occur at a faster rate at a given temperature, including low temperatures. However, the thermodynamic favorability of the reaction, as determined by delta "G", remains unchanged.
