• # question_answer 63) For the reaction ${{C}_{3}}{{H}_{8}}(g)\,\,+\,\,5{{O}_{2}}(g)\,\,\to 3C{{O}_{2}}(g)\,\,+\,\,4{{H}_{\text{2}}}\text{O(}\ell \text{)}$ at constant temperature, $\Delta H\,\,-\,\,\Delta U$ is- A) $-RT$              B) $RT$C) $-3RT$            D) $+3RT$

$\Delta H=\Delta U+\Delta ngRT$
