Which of the following is a description of an example of the second law of thermodynamics? Some chemical energy in glucose transforms to chemical energy in ATP. The kinetic energy of wind turns the blades of a wind turbine. The chemical energy in gasoline is transformed to kinetic energy to drive a car. The mechanical energy of flowing water turns a turbine. Some chemical energy in gasoline is transformed to heat while driving a car.

SECTION 1: ACTIVATION ENERGY The picture to the right shows someone trying to push a boulder up a hill. In order for the boulder to reach its final destination at point B, it must be pushed to the top of the hill because once it reaches the top of the hill it will roll down the rest of the way. A similar scenario exists in chemistry, before a chemical reaction will take place, energy must be put into the system. The energy needed for a chemical reaction to move from point A to the top of the hill is known as activation energy, also written as Ea. Increasing Energy. Activation Energy Activation Energy Energy Content of Reactants A + B Reactants FIGURE 3 J Progress of Reaction. t $ Uncatalyzed Reaction (without enzyme) Energy Content of Products V FIGURE 2 Catalyzed Reaction (with enzyme) C + D Products A م اسکار (TIME) 3. Compare Figure 3 above to the Figure 1 (comparing the heights of 2 mountains), determine how using an enzyme in a chemical reaction impacts the reaction by answering…

Name 3 nonrenewable sources of energy. In your own words, please discuss at least 3 pros and 3 cons of each,

What these letters represent? This picture is the effect of the energy graph.

When ATP is formed: A Entropy occurs B Kinetic energy is being transformed into potential energy An endergonic reaction is taking place D All of these

NaCl (s) -> NaCI (aq) is accompanied by an increase in entropy because [Select] [Select] a solute was dissolved in water, forming a solution the number of products is greater than the number of reactants the phase change from vaporization is towards a higher internal energy

Which of the following is true of thermodynamically spontaneous reactions? O A. They are all energy-yielding They are all energy-consuming They all result in an increase in the temperature of the system They all result in a decrease in the temperature of the system В.

How it is that cells are making larger, more complex molecules, yet they do not defy the second law of thermodynamics? (note: cells are open systems not closed)
