Identify the INVALID equation.

Options

  1. A∆ H = ∑ H p r o d u c t s - ∑ H r e a c t a n t s
  2. B∆ H = ∆ U + P∆ V
  3. C∆ H ( r e a c t i o n ) o = ∑ H ( p r o d u c t b o n d s ) o - ∑ H ( r e a c t a n t b o n d s ) o
  4. D∆ H = ∆ U + ∆ n R T

Correct answer

C. ∆ H ( r e a c t i o n ) o = ∑ H ( p r o d u c t b o n d s ) o - ∑ H ( r e a c t a n t b o n d s ) o

Step-by-step solution

∆ H ( r e a c t i o n ) o = ∑ H ( r e a c t a n t b o n d s ) o - ∑ H ( p r o d u c t b o n d s ) o
