Q40 / 150 · MHT CET 2017 · Chemistry

Identify the INVALID equation.

A
$∆ H = \sum H_{p r o d u c t s} - \sum H_{r e a c t a n t s}$
B
$∆ H = ∆ U + P∆ V$
Correct answer
C
$∆ H_{(r e a c t i o n)}^{o} = \sum H_{(p r o d u c t b o n d s)}^{o} - \sum H_{(r e a c t a n t b o n d s)}^{o}$
D
$∆ H = ∆ U + ∆ n R T$

Solution

∆ H_{(r e a c t i o n)}^{o} = \sum H_{(r e a c t a n t b o n d s)}^{o} - \sum H_{(p r o d u c t b o n d s)}^{o}

Hence, the correct answer is option: 'C'.
