If the standard cell potential E°cell is positive, the equilibrium constant K of the reaction is:

Answer: greater than 1.

  • A less than 1
  • B greater than 1
  • C equal to 1
  • D equal to zero

Correct answer: B. greater than 1

Explanation: A positive E°cell means a negative ΔG°, so K > 1 and products are favoured.
