Define rate of reaction? Write two factors that affect the rate of reaction.
Rate of Reaction: rate of reaction may be defined as the change in concentration of a substance divided by the time interval during which this change is observed:
Factors Affecting Rate of Reaction
1. Concentration of reactants
2. Temperature
3. Catalyst
Arrange the following in increasing order of their basic strength:
(i) C6H5 – NH2, C6H5 – CH2 – NH2, C6H5 – NH – CH3
Why does a solution containing non-volatile solute have higher boiling point than the pure solvent? Why is elevation of boiling point a colligative property?
