Answer:
1) As the temperature increased what happened to the N2O4 concentration, it decreased
2) Formation of products, products are the right hand side of the equation.
3) Right to left is exothermic
4) Change in enthalpy N2O4 ⇔2NO2, HR = -14 kcal
As it's an exothermic reaction, the enthalpy of the reactants is higher than the products and the sign of the HR will be negative.
Explanation:
N2O4 ⇔2NO2
(colorless) (reddish-brown)
1) As the temperature increased what happened to the N2O4 concentration, it decreased
2) Formation of products, products are the right hand side of the equation.
3) Right to left is exothermic
4) Change in enthalpy N2O4 ⇔2NO2, HR = -14 kcal
As it's an exothermic reaction, the enthalpy of the reactants is higher than the products and the sign of the HR will be negative.
