Give the name of the following reaction:
`C_(2)H_(5)Br+C_(2)H_(5)ON a to C_(2)H_(5)OC_(2)H_(5)+NaBr`

A

`-64.81`

B

`-190.71`

C

`-209.41`

D

`-224.38`

Text Solution

Verified by Experts

The correct Answer is:
C
`Deltan_(g) = 1-2=-1`
`DeltaE = DeltaH -Deltan_(g)RT = DeltaH-RT = -72.3 + 8.314 xx 300 xx 10^(-3) = -69.806 kJ//"mol"`
So for 3 mole we will get `DeltaE = -69.806 xx 3kJ//"mole" = -209.42 kJ//mol`
