Question
Chapter 2.1, Problem 2.3E
Interpretation Introduction
Interpretation: The simple potential energy diagram that indicates substrates, products and transition state involved in pyrolysis reaction of chloroethane should be drawn.
Concept introduction: Potential energy diagram describes plots of energy against reaction coordinate. The initial rise in energy until the transition state is equivalent to barrier that must be overcome in order for the reaction to proceed. The energy that must be provided equivalent to this energy gap is termed as activation energy. The various quantitative aspect of this potential energy curve helps to determine the rate of establishment of equilibrium for a certain reaction.

2b) Which of these, the activation energy or the net free energy change, determines whether a reaction is chemically defined as "spontaneous"?
For the reaction ABC + D⇌ AB +CD, ΔHrxn°=-55 kJ/mol and Ea(fwd)=215 kJ/mol. Assuming a one-stepreaction, (a) draw a reaction energy diagram; (b) calculate Ea(rev);and (c) sketch a possible transition state if ABC is V-shaped.step, (a) draw a reaction energy diagram; (b) calculate ΔHrxn°;and (c) sketch a possible transition state
Which statement is NOT true?
ΔH° determines the height of the energy barrier.
Two reactions can have identical values for ΔH° but very different Ea values.
The lower the activation energy, the faster the reaction.
The larger the activation energy, the slower the reaction.

- Cobalt(II) chloride hexahydrate, CoCl26H2O, is a bright pink compound, but in the presence of very dry air it loses water vapor to the air to produce the light blue anhydrous salt CoCl2. Calculate the standard free-energy change for the reaction at 25C: CoCl26H2O(s)CoCl2(s)+6H2O(g) Here are some thermodynamic data at 25C: What is the partial pressure of water vapor in equilibrium with the anhydrous salt and the hexahydrate at 25C? (Give the value in mmHg.) What is the relative humidity of air that has this partial pressure of water?

The first of these compounds is silane, SiH4, which is used in the electronics industry to produce thin ultrapure silicon films.
