11. Energy of reaction, q, differs from reaction enthalpy, AH, in the following ways:
a. q is a constant and has units of kJ/mol or kJ/g, while 4H is reaction-specific and has units of J.
b. q is a constant and has units of J, while 4H is reaction-specific and has units of kJ/mol or kJ/g.
c. q is reaction-specific and has units of J, while AH is a constant and has units of kJ/mol or kJ/g.
d. q is reaction-specific and has units of kJ/mol or kJ/g, while 4H is a constant and has units of J.
