Question

U THERMODYNAMICS
An adiabatic reversible process is one in which :-
(1) Temperature of the system does not change
(2) The system is not closed to heat transfer
(3) There is no entropy change
(4) None of these
no
be
Entropy means
(1) Disorderness
(2) Randomness
(3) Orderness
31.
(4) both 1 & 2
32. AS for the reaction;
MgCO3(s) - MgO(s) + CO,(g) will be :
(1) (2) -ve (3) tve (4) oo
33. When the egg is hard boiled, there is-
(1) Increase in disorder
(2) Decrease in disorder
(3) No change in disorder
(4) AG is negative
2)
34. If Sº for H, Cl, and HCl are 0.13, 0.22 and
0.19 kJ K-1 mol-1 respectively. The total change in
standard entropy for the reaction
H + Cl, → 2HCl is :
K-1 mol-1
(2) 40 JK-1 mol-1
(3) 60 JK-1 mol-1 (4) 20 JK-1 mol


As requested, Thermodynamics.​

Answer 1

Answer:1) 3... adiabatic process is isoentropic...

2) 4

3)+ve

4) increase in disorder bcz of denaturation of protein molecules

5)2×0.19-(0.13+0.22)

Explanation:I hope it's helpful

Answer 2

Explanation:

in adiabatic no change in entropy

entropy means both disordernesss and randomness

change in s is positive.. as gas is formed

when egg is boiled disorderness decrease change in s is negative
