Consider the following processes :-
`{:(,DeltaH(kJ//mol)),((1)/(2)A rarr B,+150),(3B rarr2C+D,-125),(E+A rarr 2D,+350),("For "B+D rarr E+2C",",Delta H" will be"):}`

A

`525 kJ//mol`

B

`-175 kJ//mol`

C

`-325 kJ//mol`

D

`325 kJ//mol`

Text Solution

Verified by Experts

The correct Answer is:
B
Desired equation in `B+DtoE+2C`, `DeltaH=?`
`2xx "Equation "(i)+"Equation"(ii)-"Equation"(iii)`
`=` Desired equations
`:. DeltaH=2xx150+(125)+(-125)-350`
`=-175 kJ// mol`
