Question 2 Consider the following voltaic cell at 298K. Select only the statements that are TRUE. Cu (s) I Cu2+ (1.0 M) II A1³+ (1.0 M) I AI (s) Al³+ (aq) + 3 e →→ Al(s) Ered=-1.66V Cu2+ (aq) + 2e →→ Cu(s) Ered = 0.34V The reducing agent is Al³+ (aq). In the Nernst equation, the value of n = 5. The anode is Cu(s). Al³+ (aq) is reduced. Question 1 Consider the following voltaic cell at 298K. Select only the statements that are TRUE. Mg (s) 1 Mg2+ (1.0 M) II A13+ (1.0 M) I Al (s) Al3+ (aq) + 3 e →→Al(s) Ered = -1.66 V Mg2+ (aq) + 2 e→→Mg(s) Ered = -2.38 V The reaction is spontaneous in the reverse direction. The standard AG° must be positive. The equilibrium constant, K, for this reaction will be greater than 1. The standard Ecell must be positive.

please help me with these four questions. i will really appreciated it
Question 4 Consider the following voltaic cell at 298K. Select ONLY the conditions in which Ecell O > E° cell. Mg (s) | Mg2+ (1.0 M) II A1³+ (1.0 M) I Al (s) Al³+ (aq) + 3 e →→ Al (s) Mg2+ (aq) + 2 e → Mg (s) Ered = -1.66V Ered = -2.38 V The mass of Mg (s) is increased to 2g. The concentration Al³+ (aq) is increased to 2M. The concentration Mg2+ (aq) is increased to 2M. The concentration Al³+ (aq) is decreased to 0.5M. Question 3 At equilibrium, the standard cell potential is equal to zero for all redox reactions. True False
