Detailed Solution

Lesser the Eo value of redox couple, higher is the reducing power.                Cu2++2e−⟶CuE∘=0.34V2H++2e−⟶H2E∘=0.00V      Since, 2H+/ H2 has lesser SRP than Cu2+ /Cu redox couple. Therefore,(i) This redox couple is a stronger oxidising agent than H+/H2.(ii) Cu cannot displace H2 from acids.
