2.
Define the following terms.
3.
Which law of thermodynamics deals with equivalence of different forms of energies?
4.
In the equation N2(g)+ 3H2(g) ⇌2NH3(g) What would be the sign of work done?
5.
For a reaction, 2Cl(g) ⟶ Cl2, What are the signs of ΔH and ΔS?
1.
The method of operation which can bring about the change in the system is called thermodynamic process.
Eg: Heating, cooling, expansion, compression, fusion, vaporization etc.,
2.
(i) System: A system is defined as any portion of matter (or universe) under thermodynamic.consideration, which is separated from the rest of the universe by real or imaginary boundaries.
(ii) Surroundings: Everything in the universe that is not the part of system and can interact with system is called as surroundings.
(iii) Boundary: Anything which separates the system from its surroundings is called boundary.
3.
First law of Thermodynamics.
4.
Work is done on the system due to decrease in volume so the sign of work done will be +ve.
5.
The given reaction represents the formation of bonds. Hence energy is released, ie. ΔH is -ve.
Further two moles of atoms will have greater randomness than one mole of molecules. Hence randomness increases so ΔS = +ve.
