Consider the following processes:
\( \begin{array}{lr} & \Delta H(\mathrm{~kJ} / \mathrm{m} \\ 1 / 2 A \longrightarrow B & +150 \\ 3 B \longrightarrow 2 C+D & -125 \\ E+A \longrightarrow 2 D & +350 \\ \text { For } B+D \longrightarrow E+2 C, \Delta H \text { will be: }\end{array} \)
[AIPMT (Mains) 2011]
(a) \( 525 \mathrm{~kJ} / \mathrm{mol} \)
(b) \( -175 \mathrm{~kJ} / \mathrm{mol} \)
(c) \( -325 \mathrm{~kJ} / \mathrm{mol} \)
(d) \( 325 \mathrm{~kJ} / \mathrm{mol} \)
