What is a transition state? How is the concept of a transition state used in activated complex theory?

Water in an open beaker evaporates over time. As the water is evaporating, is the vapor pressure increasing, decreasing, or staying the same? Why?

In a parallel reaction in which two products can be formed from the same reactant, what determines the extent to which one product will be formed over another?

What is a half-life? Is the half-life for a first-order reaction dependent on concentration?

What is the difference between a first-order reaction and a second-order reaction?

Consider the reaction A $\to$ B The rate of the reaction is 1.6 × 10^-2 M/s when the concentration of A is 0.35 M. Calculate the rate constant if the reaction is (a) first order in A and (b) second order in A.

What is the method of initial rates, and why is it used in chemical kinetics studies?

What is the difference between the order of a reaction with respect to a given species and the overall order?

Why is the stoichiometry of a reaction generally not sufficient to determine reaction order?

Which of the following research designs will allow cause-and-effect conclusions?

A) correlational studies

B) experimental

C) quasi-experimental

D) archival

How do concentrated basic solutions differ from other basic solutions?

What are [H3O+], [OH?], and pH in a solution with a pOH of 5.65?

Why is fusion an endothermic process, but freezing is an exothermic process?

Prove or disprove. For every positive integer n, $n^{2}-n+11$ is a prime.
