How does an increase in temperature affect rate of reaction? Explain this effect in terms of the collision theory of the reaction rate.

Compare the Bohr theory with the Schrodinger treatment of the hydrogen atom. Comment specifically on the total energy and orbital angular momentum.

Describe the four parts of reasoning in Darwin's theory of evolution by natural selection. Use examples in your answer.

According to the rational voter theory, will the following increase or decrease voter turnout?

c. The number of polling stations increases.

Bohr described the hydrogen atom as an electron orbiting a hydrogen nucleus. Although certain aspects of his theory are still valid, his theory agreed quantitatively with experiment only in the case of the hydrogen atom. In what way does quantum mechanics change Bohr's original picture of the hydrogen atom?

What is the neutral theory of molecular evolution as proposed by Kimura (1968)? What determines the frequency of neutral alleles in a population?

Describe the Theory of Reasoned Action. Why might it not be equally valuable when we apply it to non-Western cultures?

How are acids and bases defined in the Arrhenius theory? Differentiate between hydrogen ions, hydronium ions, and hydroxide ions.

What is the difference between a hypothesis, a law, and a theory? $1.206 \times 10^{-23}$ expressed to the power of $10^{-25}$?

Does VB theory indicate that the diatomic molecule $\mathrm{He}_2$ is a viable species? Rationalize your answer.

a. How is the VSEPR theory used to classify molecules? b. What molecular geometry would be expected for

$$F_2$$

and HF?

Use the kinetic molecular theory to draw a molecular-level picture of a gas. Briefly describe the motion of the gas particles.

Correct each of the following misstatements from Dalton’s atomic theory.

a. Elements are made of tiny particles called molecules.
