Category 1 $400 What phase change occurs during sublimation? Category 1 $600 Why is the heat of vaporization of water greater than the heat of fusion? Category 1 $800 What amount of heat energy is absorbed when 50 g of water is heated from 10C to 20C? Category 1 $1000 Describe section AB and BC. Include as much detail as possible. Category 1 $200-Answer Average kinetic energy Category 1 $400-Answer Solid to Gas Category 1 $600-Answer The change from liquid to gas requires more energy. Category 1 $800-Answer 2090 J Category 1 $1000-Answer AB – Heat of fusion, MP/BP, PE inc, KE constant BC – KE inc, PE constant, LIQUID Category 2 $200 A gas is at 300K and 0.25 atm How could you make this gas behave more like an ideal gas? Category 2 $400 Compare the number of molecules in two 1.5L samples of gas at STP. Category 2 $600 A closed 1 L system contains H2 gas. How will an increase in temperature effect the pressure in the container. Category 2 $800 Compare the entropy of H2O(g) to H2O(s) Category 2 $1000 Describe an ideal gas according to the Kinetic Molecular Theory. Your answer must include 4 pieces of information. Category 2 $200-Answer Decrease temperature, increase pressure Category 2 $400-Answer The number of molecules are the same in both gases. Category 2 $600-Answer The pressure will increase. Category 2 $800-Answer The entropy of the gas is higher because gases are more disordered. Category 2 $1000-Answer 1. Particles have random motion 2. No attraction between particles. 3. Particles are small compared to the space between them. 4. Particles will collide and transfer energy, but overall, energy is conserved. Category 3 $200 Describe the energy and entropy trends that exist in nature. Category 3 $400 What 2 conditions describe systems that have reached equilibrium? Category 3 $600 How does the addition of a catalyst impact the activation energy and rate of reaction? Category 3 $800 What conditions must be met for an effective collision between particles to occur? Category 3 $1000 Label A and B and indicate whether this reaction is endothermic or exothermic? Category 3 $200-Answer Systems tend towards high entropy and love energy. Category 3 $400-Answer 1. The system must be closed. 2. There are equal amounts of reactants and products. Category 3 $600-Answer Catalysts decrease activation energy and increase the rate of reaction. Category 3 $800-Answer Proper energy and orientation. Category 3 $1000-Answer A – activation energy of forward reaction. B – Heat of reaction Endothermic Category 4 $200 Define oxidation. Category 4 $400 What is reduction? Category 4 $600 Describe the energy conversion that occurs in electrolytic and voltaic cells. Category 4 $800 Describe the reaction that occurs at the anode and cathode of an electrolytic cell. Category 4 $1000 This equation describes a reaction at equilibrium. For the forward reaction: 1. Which substance oxidized? 2. Which substance is reduced? Category 4 $200-Answer LEO – when an atom loses electrons! Category 4 $400-Answer GER – when an atom gains electrons. Category 4 $600-Answer Electrical energy is converted to chemical energy. Category 4 $800-Answer Oxidation occurs at the anode. Reduction occurs at the cathode. Category 4 $1000-Answer 1. Chlorine is reduced. 2. Hydroxide is oxidized.
