From the given information, what is the standard enthalpy of formation for `Al_(2)O_(3)(s)` ?
`2Al_(2)O_(3)(s)to4Al(s)+3O_(2)(g),DeltaH_(rxn)^(@)=3352kJ`

A

`-6704kJ//mol`

B

`-3352kJ//mol`

C

`-1676kJ//mol`

D

`1676kJ//mol`

Text Solution

Verified by Experts

The correct Answer is:
C
`T.R : 2Al_(s)+(3)/(2)O_(2(g))toAl_(2)O_(3(s),DeltaH_(r)=DeltaH_(f)`
`DeltaH_(f)-(3352)/(2)=1676kJ//mol`
