(ii) the cu2+ ions are attracted to the negative electrode, where they are reduced to produce copper atoms.
write a balanced half equation for the reaction at the negative electrode.

(1)

(iii) suggest a suitable electrolyte for the electrolysis.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
