Q. For redox reaction, $F e^{2 +} (a q) + C r_{2} O_{7}^{2 -} (a q) + H^{+} (a q)$ $F e^{3 +} (a q) + C r^{3 +} (a q) + H_{2} O (l)$ The coefficients of $F e^{2 +}, C r_{2} O_{7}^{2 -}$ and $H^{+}$ in the balanced reaction are

$6, 1, 14$

$3, 2, 6$

$2, 3, 6$

$6, 4, 12$

$6 F e^{2 +} (a q) + C r_{2} O_{7}^{2 -} (a q) + 14 H^{+} (a q)$ $6 F e^{3 +} (a q) + 2 C r^{3 +} (a q) + 7 H_{2} O (l)$
