  = 0.4300 kJ/mol-K = 4300 J/mol-K. The reaction added heat to the surroundings so the entropy went up. In problem 5a you calculated So for this reaction ( Sosys). Copy the answer here: -333.1 J/mol-K. The first law of thermodynamics says the Hsurr = - Hsys. Notice that Ssurr ≠ - Ssys for this reaction (entropy is NOT conserved!)

  Also, note that the standard heat of formation for an element in its standard state always has a value of 0 kJ/mol. Let's look at a problem in which the heat of reaction is calculated from the heats of formation. Suppose you are given the following balanced chemical equation and were asked to find the heat of reaction and determine whether the ...
