What is meant by the rate of reaction
The rate of reaction refers to the speed at which a reaction
proceeds.
An increase in temperature will cause the rate of a chemical reaction to
increased temperture causes rate or reaction to increase.
What happens to the reaction rate as the reactants get used up in a reaction
The rate of the reaction begins to decrease as reactants are
used up
Which equation is an expression of the rate law
What does it mean if keq1
I suspect it could be " k eq 1" , or "k =1".
What information does an equilibrium constant give about a reaction
It tells whether products or reactants are favored at
equilibrium
What causes the reaction rate to decrease as the reaction progresses
The concentration of the reactants decreases.
How does increasing the temperature affect a reaction
Increasing temperature affects a reaction in two ways:
1) at higher temperatures the molecules are moving around faster
and collisions and reactions are more frequent, so the reaction -
both forward and reverse - speed up.
2) at higher temperatures, the equilibrium state will shift. In
some cases it will shift the equilibrium towards the product. In
other cases, it will shift it back towards the reactants.
What is the rate constant of a reaction if rate 1 10-2 molLs A is 2 M B is 3 M m 2 and n 1
What describes a reaction that reaches equilibrium
The product and reactants reach a final, unchanging level.
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.
A prosthesis may be nonbiocompatible or otherwise endanger the
well-being of the patient it is intended to help.
What is the name of the field of study with laws that describe how energy is transferred to different locations and forms
What increases the chance of reaction when two molecules collide
increasing the concentration in the molecue
Which of these correctly lists the order of the engineering process
Identify a need, research the background, make a plan, do the
work, evaluate the results, look for improvements. (APEX)
Which of the following best describes a bronsted lowry acid base reaction
Acid + Base = Salt+Water (APEX)
How can the placebo effect cause problems in an experiment
The placebo effect can causes the dependent variable to change
without any causative reason. This distorts the results for the
control set in an experiment.
A scientist has just developed a composite drug to fight seasonal allergies. What is the next step in the engineering process before the drug is released
Testing the composite drug in a trial run.
The process of using computers and robots to conduct thousands of tests to determine the interaction between different compounds and a disease is called what
High-throughput screening
A scientist is giving patients a sugar pill that has no medical properties. What is this pill called
What of the following is a characteristic of a weak acid
It does not dissociate completely in water
What does it mean if Keq is less than 1
Reactants are favored over products in the reaction.
