Question #1fad2
1 Answer
For a reaction to be feasible the total entropy change of the system and surroundings must be positive.
To work out the entropy change in the system we need to find the total entropy of the products and subtract this from the total entropy of the reactants.
You can get these data from standard tables:
Now we need to work out the entropy change in the surroundings which would result if this reaction were to happen.
This is given by:
Now we need to add these two together:
The negative value of
