Question 1

Consider the following equilibrium reaction.Ni2+(aq) + Sn(s) Ni(s) + Sn2+(aq)The forward reaction is non-spontaneous. What does this indicate about the relative strengths of the reducing and oxidizing agents on each side of the equation?

Revolt · Accepted Answer

The stronger agents are on the right side of the equation.

Question 2

Which best describes the oxidizing agent in this reaction? Cl2(aq) + 2Br–(aq) 2Cl–(aq) + Br2(aq)

Revolt · Accepted Answer

Chlorine (Cl) is the oxidizing agent because it gains an electron.

Question 3
