Consider the following redox reaction taking place in acidic medium:
\[
\mathrm{BH_4^- (aq) + ClO_3^- (aq) \rightarrow H_2BO_3^- (aq) + Cl^- (aq)}
\]
If the Nernst equation for the above balanced reaction is
\[
E_{\text{cell}} = E^\circ_{\text{cell}} - \frac{RT}{nF}\ln Q,
\]
then the value of \(n\) is ________ (Nearest integer).
