Classify the molecules based on whether the molecule has a standard enthalpy of formation, AH;, equal to 0. Assume all
1 answer:
The standard enthalpy of formation of substance in its standard state is zero.
Enthalpy is defined as a thermodynamic quantity that describes the energy of a system. For substances in their standard state, the enthalpy of formation is zero.
The standard state of a substance is defined as the state in which it is found under standard conditions. The following substances has their standard ethalpy of formation as zero or not zero;
Zero enthalpy of formation Non zero enthalpy of formation
Cl2(g) I2(s)
Br(g) Br2(l)
I2(g) Br2(s)
Hg(l) Hg(s)

Answer:
C. More NO2 and SO2 will form
Explanation:
Le Chatelier's Principle : It predicts the behavior of equilibrium due to change in pressure , temperature , volume , concentration etc
It states that When external changes are introduced in the equilibrium then it will shift the equilibrium in a direction to reduce the change.
In given Reaction SO3 is introduced(increased) .
So equilibrium will shift in the direction where SO3 should be consumed(decreased)
Hence the equilibrium will go in backward direction , i.e
So more and more Of NO2 and SO2 will form
