1.

(a) Give any two differences between lyophilic and lyophobic colloids. (b) Write the two steps involved in the mechanism of enzyme catalysed reaction. (c) What is the entropy change (Delta s) for adsorption ?

Answer»

Solution :(a)
(b) Step 1 : Binding of enzyme to substrate to FORM an activated complex
`E + S to ES^(**)`
Step 2 : DECOMPOSITION of the activated complex to form product
`Es^(**) to E + P`
(C) Decreases OR `Delta S = -ve OR DeltaS < O OR Delta S` is negative.
