Assume each reaction is carried out in open container. For which reaction will \Delta H=\Delta E?

Option: 1

C_{\left ( s \right )}+2H_{2}O_{\left ( g \right )}\rightarrow 2H_{2}O_{\left ( g \right )}+CO_{2}_{\left ( g \right )}


Option: 2

PCl_{5\left ( g \right )}\rightarrow PCl_{3\left ( g \right )}+Cl_{2\left ( g \right )}


Option: 3

2CO_{\left ( g \right )}+O_{2\left ( g \right )}\rightarrow 2CO_{2\left ( g \right )}


Option: 4

H_{2\left ( g \right )}+Br_{2\left ( g \right )}\rightarrow 2HBr_{\left ( g \right )}

\Delta H=\Delta E+\Delta ng\, RT

if\, \Delta ng=o

then\, \, \Delta H=\Delta E

H_{2}\left ( g \right )+Br_{2}\left ( g \right )\rightarrow 2HBr\left ( g\ \right )\Delta ng=o

Option (4) is correct answer
