Calculate the entropy change for the surroundings of the reaction below at 350k: n2(g) + 3h2(g) -> 2nh3(g) entropy data: nh3 = 192.5 j/mol k h2 = 130.6 j/mol k n2 = 191.5 j/mol k

Answer : The entropy change for the surroundings of the reaction is, -198.3 J/K

Explanation :

We have to calculate the entropy change of reaction .

where,

= entropy of reaction = ?

n = number of moles

= standard entropy of

= standard entropy of

= standard entropy of

Now put all the given values in this expression, we get:

Therefore, the entropy change for the surroundings of the reaction is, -198.3 J/K

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
