Questions + Answers key
Take MCQ Chemistry Test1.
What is absolute zero temperature?
2.
What are spontaneous processes?
3.
Define entropy of transition.
4.
Define entropy of vapourisation.
5.
Define entropy of fusion.
1.
The lowest hypothetical or imaginary temperature at which gases are supposed to occupy zero volume is called absolute zero.
2.
A reaction that occurs under the given set of conditions without any external driving force is called a spontaneous reaction.
Spontaneous (irreversible)
ΔH<0
ΔS>0
ΔG<0
3.
When one mole of a solid changes reversibly from one allotropic form to another at its transition temperature. The entropy change is given
\({ \triangle S }_{ t }=\frac { { \triangle H }_{ t } }{ { T }_{ t } } \)
Where ΔHt is "the Molar heat of transition, Tt is transition temperature.
4.
The heat absorbed, when one mole of liquid is boiled at its boiling point reversibly, is called molar heat of vapourisation. The entropy change is given by
\({ \triangle S }_{ v }=\frac { { \triangle H }_{ v } }{ { T }_{ b } } \)
where ΔHv is Molar heat of vaporisation. Tb is boiling point.
5.
The heat absorbed, when one mole of a solid melts at its melting point reversibly, is called molar heat of fusion. The entropy change is given by
\({ \triangle S }_{ f }=\frac { { \triangle H }_{ f } }{ { T }_{ f } } \).
Where ΔHf is molar .heat of fusion. Tf is melting point.
