What is gibbs free energy? a) the result of the product of the temperature and entropy of a change, subtracted from the enthalpy of the change. b) the result of the product of the temperature and enthalpy of a change, subtracted from the entropy of the change. c) the result of the product of the temperature and entropy of a change, added to the enthalpy of the change. d) the result of the product of the temperature and enthalpy of a change, added to the entropy of the change.

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
