Question

Which two values will a spontaneous reaction have?

Answer 1

Answer:

-∆G and +Eocell

Explanation:

For an electrochemical reaction to be spontaneous, the change in free energy must be negative. This applies to all chemical reactions as a basic condition for spontaneity of chemical reactions.

More particular to an electrochemical cell is the value of the standard cell voltage. A positive value of standard cell voltage implies a spontaneous electrochemical reaction.

Answer 2

-∆G and +Eocell are spontaneous.

Always Remember: The higher the value of the EMF of a cell then it means the driving force for the reaction to occur is also high.
