Question

For which of the following change $\Delta$H ¹$\Delta$E ?

• A. H2(g) + I2(g) $\longrightarrow$ 2HI(g)
• B. HCl(aq) + NaOH(aq) $\longrightarrow$NaCl(aq) + H2O($\mathcal{l}$)
• C. C(s) + O2(g) $\longrightarrow$ CO2(g)
• D. N2(g) + 3H2(g) $\longrightarrow$2NH3(g)

Answer 1

Answer: (D)

N2(g) + 3H2(g) $\longrightarrow$2NH3(g)

Answer 2

using $\Delta$H = $\Delta$E + $\Delta$ngRT
