For the equilibrium,
`2H_(2)O hArr H_(3)O^(+) + OH^(-)`,the value of `DeltaG^(@)`at 298 K is approximately:

For the equilibrium (autoprotolysis of water), 2H_(2)O iff H_(3)O^(+)+OH^(-) , the value of DeltaG^(0) at 298 K is approximately?

For the equilibrium H_(2) O (1) hArr H_(2) O (g) at 1 atm 298 K

For the equilibrium H_(2) O (1) hArr H_(2) O (g) at 1 atm 298 K

In the equilibrium HClO_(4) + H_(2)O hArr H_(3)O^(+) + ClO_(4)^(-)

For the equilibrium H_(2)O(l) iff H_(2)O(g) at 1 atm and 298 K

For the equilibrium H_(2) O(l) hArr H_(2) O (v) , which of the following is correct ?
