Which statement about standard reduction potentials is correct
(1) E⁰ of H^+/H2 = Zero at all temperature
(2) E⁰ of D^+/D2 = zero at 298 K
(3) A redox reaction is feasible if sum of SRP of oxidant and that of reductant is a positive quantity
(4) K2Cr2O7(acid) acid is stronger oxidising agent than KMnO4(acid)
[Given : E⁰ of MnO4/Mn^2+ =1.51 V ;
E⁰ of Cr2O7^2-/Cr^3+ = 1.33 V]
