The answers that apply are;
- The production of ATP from ADP is non-spontaneous.
- The production of ATP from ADP is endothermic.
The formation of ATP from ADP is not spontaneous (requires energy input) and is why it requires an enzyme (ATP synthase) to reduce the activation energy and catalyze the reaction. The reaction absorbs energy and this is why ATP is used to reserve energy in the Pi bond for later use (through hydrolysis of the bond).
Answer:
As2O3 → H3AsO4
As2O3 → 2H3AsO4 balance As
5H2O + As2O3 → 2H3AsO4 balance O by adding H2O to one side
5H2O + As2O3 → 2H3AsO4 + 4H+ balance H by adding H+ to one side
5H2O + As2O3 → 2H3AsO4 + 4 H+ + 4e- balance charge by adding electrons to one side
Now do the same for the other part of the reaction
NO3- → NO
NO3- → NO + 2H2O
4H+ + NO3- → NO + 2H2O
3e- + 4H+ + NO3- → NO + 2H2O
Now cancel the electrons by multiplying the first equation by 3 and the second equation by 4, then add them together
.
3As2O3 + 4NO3- + 7H2O + 4H+ → 6H3AsO4 + 4NO
