Question

Delt G0 for a particular reaction is large negative number Ea for the same reaction is a large postive number. @ standard conditions.

a. Reaction is spontaneous but will proceed slowly

b.Reaction will rapidly go to completion

c. this is an explosivley exothermic reaction.

d.this is not a spontaneous reaction

II. Strongest reducing agent ?

Standar reduction potentials

Na+ + e- = Na E0 = -2.71 V

Mg2+ + 2e- = Mg E0=-2.37 V

a. Mg b. Mg2+ c. Na d. Na+

V. whoch correctly distinguishes a voltaic cell from an electrolytic cell ?

Electrolytic ,Voltaic

a. anode is postive, anode is negative

b.reduction at cathode, reduction at anode

c. Delta G <0, Delta G >0

d.Kinetics are slow, Kinetics are fast

Delt G0 for a particular reaction is large negative number Ea for the same reaction is a large postive number. @ standard conditions.

a. Reaction is spontaneous but will proceed slowly; since it requires a lot of energy to react, i.e. to break the barrier

b.Reaction will rapidly go to completion

c. this is an explosivley exothermic reaction.

d.this is not a spontaneous reaction

II. Strongest reducing agent ?

Standar reduction potentials

Na+ + e- = Na E0 = -2.71 V

Mg2+ + 2e- = Mg E0=-2.37 V

a. Mg b. Mg2+ c. Na d. Na+

strongest reducing agent ---> easiest to oxidize, i.e. the lowest E° potential

then

choose Na(s) , it is likely to oxidize to form Na+ faster

V. whoch correctly distinguishes a voltaic cell from an electrolytic cell ?

Electrolytic ,Voltaic

a. anode is postive, anode is negative

b.reduction at cathode, reduction at anode

c. Delta G <0, Delta G >0

In electrolysis, we need to provide electric current; in galvanic we GET electric current

d.Kinetics are slow, Kinetics are fast
