The temperature of a substance remains constant at its melting and boiling points untill all the substance melts or boils because, the heat supplied is continuously used up in changing...
(a) Working capital of a firm refers to the amount of current assets which are in excess over current liabilities. If a company has a higher working capital then there will...
(c) : According to Raoult’s law equimolal solutions of all the substances in the same solvent will show equal elevation in boiling points as well as equal depression in freezing...
(b) : For endothermic reaction, ΔH = +ve
Now, ΔG = ΔH – TΔS
For nonspontaneous
reaction, ΔG should be positive
Now ΔG is positive at low temperature if ΔH is positive.
ΔG is negative...
(i) It is due to
(a) Intermolecular hydrogen bonding in HF.
(b) Higher H—F bond dissociation enthalpy than H—Cl.
(ii) As P—P single bond (213 kJ mol-1) in P4 is much weaker than...
(i) Ethanol undergoes intermolecular hydrogen bonding due to the presence of a hydrogen attached to oxygen atom. As a result, ethanol exist as associated molecules and hence it has higher...
