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

`-325`kJ/mol

B

325kJ/mol

C

525kJ/mol

D

`-175`kJ/mol

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta H`
`(1)/(2)A rarr B " " +150` ...(i)
`3B rarr 2C + D " " -125` ...(ii)
`E + A rarr 2D " " +350` ...(iii)
`bar(B +D rarr E + 2C)`
`2xx` eq (i) + eq (ii)- eq (iii)
`Delta H= 300-125- 350= -175`
