Potential for some half cell reactions are given below. On the basis of these mark the correct answer. (i) H^(+)(aq) + e^(-) rightarrow (1/2)H^(2)(g) E_(cell)^(@) = 0.00V (ii) 2H_(2)O(l) rightarrow O_(2)(g) + 4H^(+)(aq) + 4e^(-) , E_(cell) = 1.96V (iii) 2SO_(4)^(2-)(aq) rightarrow S_(2)O_(8)^(2-)(aq) + 2e^(-), E_(cell)^(@) = 1.96V

Potential for some half cell reactions are given below. On the basis of these mark the correct answer. (i) H^(+)(aq) + e^(-) rightarrow (1/2)H^(2)(g) E_(cell)^(@) = 0.00V (ii) 2H_(2)O(l) rightarrow O_(2)(g) + 4H^(+)(aq) + 4e^(-) , E_(cell) = 1.23V (iii) 2SO_(4)^(2-)(aq) rightarrow S_(2)O_(8)^(2-)(aq) + 2e^(-), E_(cell)^(@) = 1.96V

The reaction, 2H_(2)O_((l)) to 4H_((aq))^(+)+O_(2(g))+4e^(-) is

Will the heat released be same or different in the following two reactions: (i) H_(2)(g) + 1/2 O_(2)(g) to H_(2)O(l) (ii) H_(2)(g) + 1/2 O_(2)(g) to H_(2)O(g) Explain.
