Question

True/False: 1. Nuclear fission is the process in which a heavy nucleus (mass number>200) divides to form smaller nuclei of intermediate mass and one or more protons?

2.In living systems, thermodynamically favorable reactions provide the free energy needed to drive necessary but thermodyncamically unfavorable reactions?

3. As chemical reactions proceeds toward equilibrium, the free energy of the system decreases at constant temperature and constant pressure.

4. at equilibrium E^(o)=0 (E^(o)=Ecell)

5. McQ-What will be the values for Ecell and K for an electrolyte cell?

a.Ecell=negative and k= large value

b.Ecell=+ and k= small value

c. Ecell=- and k=small value

d.Ecell=+ and k=large value.

Thank you :))

Explanation / Answer

1. True, that is the definition of nuclear fission.2

2. True, we can use a thermodinamically favorable reaction to drive an thermodinamically unfavorable reaction

3. A chemical reaction will shift to the direction that will decrease the free energy change so this is true
