Galvanic cells

Question 1

alkaline fuel cell cathode

Answer 1

O2(g) + 2H2O(l) +4e- = 4OH-(aq)

Question 2

alkaline fuel cell anode

Answer 2

H2(g) + 2OH-(aq) = 2H2O(l) + 2e-

Question 3

What’s the maximum possible voltage generated by a fuel cell operating under standar conditions?

Answer 3

1.23V

Question 4

increase temperature: exothermic

Answer 4

a backward reaction is favoured as the system attempts to absorb the added heat.
thos would also decrease the K value as the concentration of the products increase.
