1. For a certain gas phase reaction AG° = -136.4 – T x (+0.3142) in units of kJ and K. Based on this
information is each of the following statements true or false? Indicate your choice by circling T (if the
statement is TRUE) or F (if the statement is FALSE)
a. The reaction is exothermic.
T
F
b. The entropy of the system increases during this reaction.
T
F
c. The products are lower in energy than the reactants are.
T
F
d. The bonding is stronger in the reactants than in the products.
F
e. At temperature T = 595 K the equilibrium constant K >> 1.
