Identify the invalid equation

Options

A. `DeltaH = sumH("Products") - sumH("reactants")`
B. `DeltaH = DeltaU + PDeltaV`
C. `DeltaH^(@)("reaction") = sum H^(@) ("product bonds")- sumH^(@)("reactant bonds")`
D. `DeltaH = DeltaU + DeltanRT`

Answer

C

Explanation

The valid equation is
`DeltaH^(@)("reaction") = sum H^(@)("product bonds") - sum H^(@)("reactant bonds")`
