Enthalpy is an extensive property. In general, if enthalpy of an overall reaction A→B along one route is ∆ r H and ∆ r H 1 , ∆ r H 2 , ∆ r H 3 ..... represent enthalpies of intermediate reactions leading to product B. What will be the relation between ∆ r H for overall reaction and ∆ r H 1 , ∆ r H 2 ..... etc. for intermediate reactions.
Options
- A∆ r H = ∆ r H 1 - ∆ r H 2 - ∆ r H 3 ....
- B∆ r H = ∆ r H 1 + ∆ r H 2 + ∆ r H 3 ....
- C∆ r H = ∆ r H 1 + ∆ r H 2 - ∆ r H 3 ....
- D∆ r H = ∆ r H 1 - ∆ r H 2 + ∆ r H 3 ....
Correct answer
B. ∆ r H = ∆ r H 1 + ∆ r H 2 + ∆ r H 3 ....
Step-by-step solution
Correct Option is : (B) ∆ r H = ∆ r H 1 + ∆ r H 2 + ∆ r H 3 ....
