For which process will `DeltaH and DeltaG^(@)` be expected to be most similar?

A

`2Al(s)+Fe_(2)O_(3)to2Fe(s)+Al_(2)O_(3)(s)`

B

`2Na(s)+2H_(2)O(l)to2NaOH(aq.)+H_(2)(g)`

C

`2NO_(2)(g)toN_(2)O_(4)(g)`

D

`2H_(2)(g)+O_(2)(g)to2H_(2)O(g)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) In this reaction, `DeltaS^(@)=0`
`thereforeDeltaG^(@)=DeltaH^(@)-TDeltaS^(@)`
`DeltaG^(@)~~DeltaH^(@)`.
