Answer : The internal energy change is, -506.3 kJ/mol
Explanation :
Formula used :
or,
where,
= change in enthalpy =
= change in internal energy = ?
= change in moles
Change in moles = Number of moles of product side - Number of moles of reactant side
According to the reaction:
Change in moles = 0 - 2 = -2 mole
That means, value of = 0
R = gas constant = 8.314 J/mol.K
T = temperature =
Now put all the given values in the above formula, we get
Therefore, the internal energy change is -506.3 kJ/mol
