Question
Consider the generic chemical reaction between A and B to form C. A has
a molar mass of 215.8 g/mol, B has a molar mass of 74.9 g/mol, and C has
a molar mass of 414.4 g/mol.
2A + 1B =7C
AH = -109.5 kcal/mol
%3D
Calculate the the energy absorbed or released when 2.65 grams
of A is reacted.
Enter your answer in Canvas. Express in the proper units, but enter the
number only. Show all work on scratch paper for full credit.
On your scratch paper answer the following:
1. Write out conversion factors for energy released from reacting B and
С.
2. Calculate the energy absorbed/released for B when 2.65 grams are
reacted.
3. Calculate the energy absorbed/released for C when 2.65 grams are
reacted.
4. Are the bonds formed in the products stronger that the bonds broken
in the reactants? Why or why not?
5. It this reaction endothermic or exothermic? Why or why not?
