3. Which of the following is the best description of a chemical reaction? O A. When molecules of a substance move slowly enough, they link together to form a crystalline structure. B. When two molecules collide with enough force, old chemical bonds are broken and new bonds form, resulting in one or more new substances. O C. When two molecules collide with enough force, they shatter into individual atoms. Later, these atoms join up in new combinations to form new substances. O D. When two atoms collide with enough force, their nuclei fuse together, forming new substances and releasing tremendous amounts of energy.

The diagram below shows steps in the exothermic chemical reaction of bromomethane with hydroxide to form methanol and bromide ion. The black spheres are carbon atoms, the white spheres are hydrogen atoms, the red spheres are oxygen atoms, and the blue dots are bromine atoms. Write a balanced chemical equation to represent the reaction. Draw an energy diagram similar in style to the one in question #1 of the reaction in which you label the energies of each step in the reaction and the activation energy. Your diagram should include the reactants, activation energy, transition state, and products. Indicate if it is endothermic or exothermic. You may draw this on paper and attach an image file to your assignment. Using the figures in the diagram above, include these figures A, B and C on your energy diagram at the steps of the reaction in the correct order, label each molecule in the drawings. Describe what is happening in the reaction you just drew at each phase as time…
Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic. Note: Because the sketches are only qualitative, the energies in them 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.
