Chemistry Help Use tabulated electrode potentials to calculate G for the following reaction: 2Na(s) 2H2O(l)H2(g) 2OH(aq) 2Na (aq) [Solved]

Yes, it is VERY spontaneous.

Na > Na e- E = 2.71
2H2O 2 e- > H2 2 OH- E = -0.83

Delta E = 2.71 0.83 = 1.88 Volts
You know the reaction is spontaneous because Ecell is positive.

Delta Go = n F Delta E
Delta Go = 2mol (96485 J/volt mol) (1.88 V)
Delta go = -3.62X10^5 J/mol = -326 kJ/mol

Na > Na e- E = 2.71
2H2O 2 e- > H2 2 OH- E = -0.83
