DeltaH for solid to liquid transitions f...

`DeltaH` for solid to liquid transitions for protein `A` and `B` are `2.73 kcal//mol` and `3.0 kcal//mol` .The two melting points are `0^(@)C` and `30^(@)C` respectively. The entropy changes `DeltaS_(A)` and `DeltaS_(B)` at two transition temperatures are related as

A

`DeltaS_(A) = DeltaS_(B)`

B

`DeltaS_(A) lt DeltaS_(B)`

C

`DeltaS_(A) gt DeltaS_(B)`

D

`DeltaS_(B)= (303 DeltaS_(A))/(273)`

Text Solution

Verified by Experts

The correct Answer is:
A

Protein A(s) , ProteinA (l) `Delta_(r)H_(A) = 2.73 kcal //mol`
ProteinB (S) ProteinB (l) `Delta_(r)H_(B) = 3.0 k cal//mol`
`DeltaS_(A) = (Delta_(r)H_(A))/(T_(A)) = 2.73/273 xx 10^(3) = 10 Jmol^(-1) K^(-1)` and `DeltaS_(A) = (Delta_(r)H_(B))/T_(B) = 3.03/303 xx 10^(3) = 10 J mol^(-1) K^(-1)`
