Calculate the standard enthalpy change for the reaction 2A+B⇌2C+2D Use the following data:
Substance | ΔH∘f (kJ/mol) |
A | -271 |
B | -381 |
C |
221 |
D | -495 |
Express your answer in kilojoules.
standard enthalp change = Enthalpy of products - Enthalpy of reactants
= (2*221 + 2*(-495)) - (2*-271 -381)
= 375 KJ/mol
