QAIPM-2000-Ch-2951: NEET 2000 Chemistry - Class 11 AIPM-2000-Ch-2951 Solution: For the reaction, \(C_2H_5OH(l)+3O_2(g) 2CO_2(g)+3H_2O(l)\)…

For the reaction, C2H5OH(l)+3O2(g)→2CO2(g)+3H2O(l)C_2H_5OH(l)+3O_2(g)\rightarrow 2CO_2(g)+3H_2O(l) which one is true

Multiple Choice Options

  • A ΔH=ΔE−RT\Delta H=\Delta E-RT
  • B ΔH=ΔE+RT\Delta H=\Delta E+RT
  • C ΔH=ΔE+2RT\Delta H=\Delta E+2RT
  • D ΔH=ΔE−2RT\Delta H=\Delta E-2RT

Step-by-Step Verified Solution

As we know, _ H = _ E + _ n g RT Now, _ n g = Number of gaseous moles of products � number of gaseous moles of reactions = 2 � 3 = � 1 _ _ H = _ E + (�1) RT _ H = _ E � RT
