unfavorable at all temperatures - Answers A reaction that has a +∆H and a -∆S is
favorable at low temperatures - Answers A reaction in which both ∆H and ∆S are negative is
∆G = ∆H - T∆S - Answers The equation that relates enthalpy, entropy, and free energy is
Hess's Law - Answers Which law states that the enthalpy change of a reaction equals the sum of the
enthalpy changes for each step of the reaction.
T - Answers T or F. Thermodynamics can be used to answer the question "Can two substances react
together?"
F - Answers T or F. Thermochemistry concentrates primarily on transformations of electrical energy.
T - Answers T or F. Energy is always required to break bonds.
F - Answers T or F. The stronger the bond is, the less energy will be released when it forms.
T - Answers T or F. A reaction is favorable if the free-energy change (∆G) is negative.
T - Answers T or F. Spontaneous chemical processes can produce only a limited degree of order and no
degree of complexity and information.
T - Answers T or F. The temperature of a substance that has a specific heat of 1.75 J/g ∙°C will decrease
by 1°C for every 1.75 J of heat removed per gram.
F - Answers T or F. The lower the specific heat of a substance, the more heat will be required to cause a
temperature change in the substance.
T - Answers T or F. When ice melts, its entropy increases
molar enthalpy of formation - Answers The change in enthalpy that occurs when 1 mole of a compound
is produced from its elements.
