<u>Answer:</u> The value of for the surrounding when given amount of nitrogen gas is reacted is 231.36 J/K
<u>Explanation:</u>
Entropy change is defined as the difference in entropy of all the product and the reactants each multiplied with their respective number of moles.
The equation used to calculate entropy change is of a reaction is:
For the given chemical reaction:
The equation for the entropy change of the above reaction is:
We are given:
Putting values in above equation, we get:
Entropy change of the surrounding = - (Entropy change of the system) = -(-121.77) J/K = 121.77 J/K
We are given:
Moles of nitrogen gas reacted = 1.90 moles
By Stoichiometry of the reaction:
When 1 mole of nitrogen gas is reacted, the entropy change of the surrounding will be 121.77 J/K
So, when 1.90 moles of nitrogen gas is reacted, the entropy change of the surrounding will be =
Hence, the value of for the surrounding when given amount of nitrogen gas is reacted is 231.36 J/K
