Use the above information to determine the standard heat of reaction \Delta H^o_{rxn} for this process: AB + C ightleftharpoons BC + A.

Notice that the elementary substances used for the synthesis reactions as represented in the table above are in their stable form at standard conditions (25C,1atm). The value of Hfo for liquid water, for example, indicates that 285.8kJ of energy are released every time that one mole of water is formed from the needed stoichiometric amounts of hydrogen and oxygen gases. It is important to realize that the same amount of energy will be absorbed when one mole of water is decomposed into one mole of H2(g) and half a mole of O2(g). Thus the energy needed to decompose a substance into elementary substance under standard conditions is given by Hdo=Hfo. We will take advantage of this symmetric relationship between heat of formation and heat of decomposition to calculate Hrxno for any process. Consider the following hypothetical data for these pair of generic chemical reactions: A+BABB+CBCHf=200kJ/molHf=100kJ/mol Heat of Reaction Homework = Unanswered Due Today, 1259 PM Use the above information to determine the standard heat of reaction Hrxn for this process: AB+CBC+A Select an answer and submit.
