(A) Exothermic and randomness increases
(B) Endothermic & randomness increases
(C) Exothermic and randomness decreases
(D) Endothermic & randomness decreases
Hide Solution
Verified By Collegedunia
The Correct Option is
A
Solution and Explanation
Explanation:
For exothermic reaction
Δ
H
=
negative and if randomness increases it means
Δ
S
becomes positive. Thus, according to
Δ
G
=
Δ
H
−
T
Δ
S
,
Δ
G
becomes negative so, the reaction is spontaneous.Hence, the correct option is (A).

The reaction between H$_2$ (g) and I$_2$ (g) was carried out in a sealed isothermal chamber. The rate law for the reaction was found to be:
\[ \text{Rate} = k[\text{H}_2][\text{I}_2] \]
If 1 mole of H$_2$ (g) was added to the reaction chamber and the temperature was kept constant, then predict the change in rate of the reaction and the rate constant.
