Question

Which of the following statements about the spontaneous reaction occurring in a galvanic cell is always true?

• A. ${E^{0}}_{\text{cell}}\text{ > 0, }\Delta G^{0}\text{ < 0, and Q < K}$
• B. $\text{ }{\text{E}^{0}}_{\text{cell}}\text{ > 0,}\Delta G^{0}\text{ < 0, and Q > K}$
• C. ${E^{0}}_{\text{cell}}\text{ > 0, }\Delta G^{0}\text{ > 0, and Q > K}$
• D. $E_{\text{cell}}\text{ > 0, }\Delta\text{G < 0, and Q < K}$

Answer 1

Answer: (D)

$E_{\text{cell}}\text{ > 0, }\Delta\text{G < 0, and Q < K}$

Answer 2

For spontaneous reaction in every condition

Ecell > 0, $\Delta$G < 0 and Q (reaction quotient) < K (equilibrium constant)
