formula for standard entropy

Postby Jack Papciak 2F » Mon Jan 29, 2018 4:32 pm

Is the formula for the standard entropy the same as the formula for then standard enthalpy? They seem very similar but I just want to make sure

Yes they are the same just with S replacing H

Yes, they are the same because they are both state functions.

Yes, they are similar because they are both state functions. To calculate the standard reaction entropy, you subtract the sum of the standard formation entropies of all of the reactants from the sum of the standard formation entropies of all of the products.

Adding on to this, an easy way to relate these equations is to remember the simple form of (Final - Initial). These equations are usable because state functions can be added or subtracted.

Yes, the formula for standard entropy is the same as the other standard formations we did last chapter.
