Identify the reaction for which $\Delta H \neq \Delta E$ :
- A$S_{(s)} + O_{2(g)} \longrightarrow SO_{2(g)}$
- B$N_{2(g)} + O_{2(g)} \longrightarrow 2 NO_{(g)}$
- C$H_{2(g)} + Cl_{2(g)} \longrightarrow 2 HCl_{(g)}$
- D$CO_{(g)} + \frac{1}{2} O_{2(g)} \longrightarrow CO_{2(g)}$

View Solution$A$ gas absorbs $100 \ J$ of heat and is simultaneously compressed by a constant external pressure of $1.5 \ atm$ from a volume of $8.0 \ L$ to $2.0 \ L$. The change in internal energy for the gas in Joules is $(1 \ L \cdot atm = 101.32 \ J)$.
$A$ gas occupies $1.5 \ L$ at $S.T.P.$ It is provided with $300 \ J$ of heat so that its volume becomes $2 \ L$ at a pressure of $1 \ atm$. The value of $\Delta U$ for the process is.....joule.
