Let's Apply Direction: Guided by the table above, which describes the connection of the nervous system with other body systems? How does the nervous system controls all the organ systems of the body, such as Circulatory, Digestive, Respiratory and Musculoskeletal System? Explain briefly. Write your answer on the space provided. (5 points) 5

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
