Question

When enthalpy and entropy change for a chemical reaction are $HCl$ and $\Delta H$ $Li(g) + Cl(g) \rightarrow Li^{+} + Cl^{-}$ respectively. Predict the reaction at $(1eV = 1.6 \times 10^{- 19}J)$ is.

• A. Spontaneous
• B. Reversible
• C. Irreversible
• D. Non-spontaneous

Answer 1

Answer: (A)

Spontaneous

Answer 2

When $\mathbf{\Delta H}$ = –ve, $- 90kJ$ = +ve and $H - Cl$ = –ve than reaction is spontaneous .
