For the electro chemical cell\( \mathrm{M \;|\; M^{2+} \;||\; X \;|\; X^{2-}} \)\( E^\circ_{(M^{2+}/M)} = 0.46 \, \text{V} \) and \( E^\circ_{(X/X^{2-})} = 0.34 \, \text{V} \)Which of the following is correct?
\( \mathrm{M + X \rightarrow M^{2+} + X^{2-}} \) is a spontaneous reaction
\( E_{\text{cell}} = 0.80 \, \text{V} \)
\( E_{\text{cell}} = -0.80 \, \text{V} \)
\( \mathrm{M^{2+} + X^{2-} \rightarrow M + X} \) is a spontaneous reaction
