Calculate `P-Cl` bond enthalpy
Given `: Delta_(r)H(PCl_(3),g)=306kJ //mol`
`DeltaH_("at omization")(P,s)=314kJ//mol`,
`Delta_(r)H(Cl,g)=121kJ//mol`

A

`1233.66kJ//mol`

B

`371kJ//mol`

C

`19kJ//mol`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
1

`P(s)+(3)/(2)Cl_(2)(g)rarr PCl_(3)(g)`
`306=(314+3xx1231)-[B.E.(P-Cl)xx3],`
`B.E.(P-Cl)=123.66kJ//mol`
