As, $hv =h v_0+K . E .$
$\therefore K . E .= hv - hv _{ o }$
Since $h v_0$ is constant, the maximum $K.E.$ is always less than the maximum value of energy $(h v)$ depending upon the frequency of the incident radiation.

$Cr_2O_7^{2-}$ ( $aq$ $1\,M$ ) $+ 14H^+(aq) + 6e^-$ $\rightarrow 2Cr^{+3} (aq,\,1\,M) + 7H_2O (l)$
$2NO(g) + O_2(g) \rightleftharpoons 2NO_2(g)$
The standard free energy of formation of $NO(g)$ is $86.6\, kJ/mol$ at $298 \,K.$ What is the standard free energy of formation of $NO_2(g)$ at $298\, K$ ? ($K_p = 1.6 \times 10^{12})$
