What is meant by the rate of reaction

The rate of reaction refers to the speed at which a reaction proceeds.

Which of the following best describes a neutralization reaction

Answer this question… Which of the following best describes a neutralization reaction? A. Acid + base H+ + OH- B. Acid + base salt + water C. Acid + base metal + nonmetal D. Acid + base H2O + H3O+

How can the rate constant be determined from the rate law

The rate constant is the reaction rate divided by the concentration terms.

Which of these does not describe a significant ethical dilemma in the drug industry

A drug for blood pressure is absorbed in the colon.

What causes the reaction rate to decrease as the reaction progresses

The concentration of the reactants decreases.

What happens to the entropy in the reaction I2s I2g

Entropy increases in the reaction.

Which of these describes an ethical dilemma that drug designers could face

A drug for blood pressure is absorbed in the colon. It is effective, but occasionally it can erode the colon walls.
