JEE Main 2026 · 4 Apr · Shift 2, Chemistry question 73

An electrochemical cell, consist of the following two redox couples, $\ce{M^{x+}}$(aq)/M(s) $[E^\ominus_{red}=+0.15\ \mathrm V]$ and $\ce{Fe^{3+}}$(aq)/Fe(s) $[E^\ominus_{red}=-0.036\ \mathrm V]$. The cell EMF ($E_\text{cell}$) is recorded to be 0.2057 V. If the reaction quotient of the electrochemical reaction is found to be $10^{-2}$, then the value of $x$ is ________. (Nearest integer)
[Given : M is a p-block metal and $\dfrac{2.303RT}F=0.059$ V]
