Consider the following reaction at 298 K:
faltersainse [42]

Answer :

\Delta S_{sys} = -1622.8 J/K

\Delta S_{surr} = -94.6 J/K

\Delta S_{univ} = 0 J/K

Explanation :  Given,

\Delta H = -483.6 kJ

The given chemical reaction is:

2H_2(g)+O_2(g)\rightarrow 2H_2O(g)

First we have to calculate the value of \Delta S_{sys}.

\Delta S_{sys}=\frac{\Delta H}{T}

\Delta S_{sys}=\frac{-483.6kJ}{298K}

\Delta S_{sys}=-1.6228kJ/K=-1622.8J/K

Entropy of system = -1622.8 J/K

As we know that:

Entropy of system = -Entropy of surrounding = 1622.8 J/K

and,

Entropy of universe = Entropy of system + Entropy of surrounding

Entropy of universe = -1622.8 J/K + (1622.8 J/K)

Entropy of universe = 0
