So for the energy level diagram of H2, I understand that when H2 absorbs energy, one electron would be promoted to the higher antibonding, but what exactly is the purpose of doing this?
The item itself serves as the cathode, at which the Au^3+ ions are reduced to Au(s). A piece of solid gold is used as the anode and is also connected to the power source, thus completing the circuit.

reaction begins only after a collision between the reactants. So this is an endothermic reaction, and most reactions occur when two reactants collide with each other.
