A) 1
B) 2
C) \[-2\]
D) 0
Correct Answer: C
Solution :
We know that, \[\Delta H=\Delta E+\Delta {{n}_{g}}RT\] \[\Delta H-\Delta E=\Delta {{n}_{g}}RT\] \[\Rightarrow \]\[-4.98=\Delta {{n}_{g}}\times 8.3\times {{10}^{-3}}\times 300\] \[\Delta {{n}_{g}}=\frac{-4.98}{8.3\times {{10}^{-3}}\times 300}\] \[\therefore \] \[\Delta {{n}_{g}}=-2\]You need to login to perform this action.
