(a)
Interpretation: Energy diagram that involves low energy for reactants and product while moderate-energy of intermediate should be drawn.
Concept introduction: Energetics of a reaction describes the energy associated with different components during the process of reaction. Energy diagram is a plot of energy along y-axis and reaction coordinate along x axis. Reaction proceeds when the reactant molecules collide and have proper orientation. The pathway from reactant to product involves transition state. A transition state is a hypothetical state that gives clear picture of the orientation of reactant molecules during collision that is a process of the bonds formed and broken during the reaction. Transition state is the highest energy state of a reaction.
The intermediate involved usually have higher potential energy than reactants species as they are formed transiently and fall back to form products that are more stable and hence reduced in potential energy.

- Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why.

Use a graphical method to determine if there is a relationship between specific heat and the atomic mass. a. b. C. d. e. If your graphs revealed relationship between specific heat and atomic revealed a mathematical mass, write down an equation for the relationship. Comment on the usefulness of the determination of specific heat as a method for identifying an element. Would specific heat alone give you much confidence with regard to the identity of the element? If you think measurement of another property would be needed to support an identification, what property would you measure and why? The elements listed in the table are all selected metals. The values for nitrogen, oxygen, fluorine and neon are 1.040, 0.918, 0.824 and 1.030 J/g K respectively.
