Question
Check mark if you agree or disagree with the following statement, then write a short convincing explanation to support or refute the statement No credit will be given without justification. Agree Disagree: All reactions with equilibrium constant greater than one (Keq > 1) are spontaneous. Agree Disagree: All spontaneous reactions occur quickly. Agree Disagree: The electrolysis of salt water will result in the oxidation of Na^+ at the anode. Agree Disagree A typical car batter can carry a voltage greater than 12 Volts. Agree Disagree Positive electromotive force corresponds to positive free energy and positive delta S(Universe).Explanation / Answer
1) agree as Delta G = -R*T*lnKc ;
For spontaneous reaction , delta G <0 , thus, Kc must be greater than 1
2) Agree
3) Disagree as Na+ cannot be further oxidized
4) Agree
5) Disagree as +ve EMF corresponds to -ve free energy and positive delta S(universe)
3)
