Can someone explain this questions? I am confused between A and D.
Here is how I approached this questions:
Its asking for spontaneity so I thought of G = H - TS equation.
I thought that ATP hydrolysis increases S and H so it can only be spontaneous under high temperatures. If the temperature is lowered, it may become non spontaneous.
I ruled out D because for a reaction to be non spontaneous, Keq should be small so less products made and more reactants left, meaning that ADP:ATP ratio should be small. But answer choice D is saying the opposite of that.
What am I doing wrong here?
