A) +3RT
B) -RT
C) +RT
D) -3RT
Correct Answer: D
Solution :
For the reaction, \[{{C}_{3}}{{H}_{8}}(g)+5{{O}_{2}}(g)\xrightarrow[{}]{{}}3C{{O}_{2}}(g)+4{{H}_{2}}O(\ell )\] \[\Delta n\]= number of gaseous moles of products - number of gaseous moles of reactants \[=3-6=-3\] \[\therefore \] \[\Delta H-\Delta E=\Delta nRT\] \[or\Delta H-\Delta E=\Delta nRT\] \[\therefore \Delta H-\Delta E=-3RT\]You need to login to perform this action.
