Answer 1

Here qv=-5133 kJ/mol.

Balancing the Naphthalene

C10H8 + 12O2 -----> 10CO2 + 4H 2O

No. of Mole On Product= 10
No. of Mole on the reactants side= 12

Therefore

Δn = 10 - 12 = -2

The relation between qp and qv is:
qp = qv + ΔnRT

So,
qp = -5133*103 + (-2*8.314*298)
=> qp= -5137955.144 J/mol
