What Would Be the Standard Enthalpy Change for the Reaction $\Delta$

question 59

Short Answer

What would be the standard enthalpy change for the reaction of 1.00 mole of H₂(g)with 1.00 mole of Cl₂(g)to produce 2.00 moles of HCl(g)at standard state conditions?
$\Delta$ H°_f (HCl(g))= -92.3 kJ/mol]
