The following results were obtained when the reaction represented above was studied at 25°C: A + 2B -> C + D
_
a) Determine the order of the reaction with respect to A and B.
b) Write the rate law for the reaction.
c) Calculate the value of the rate constant, k, specifying units.
d) Determine the initial rate of disappearance of substance B in Experiment 2.
_
e) Identify which of the reaction mechanisms represented below is consistent with the rate law developed in part B. Justify your choice by writing rate laws for each mechanism. Also, identify any intermediate(s) and/or catalyst(s) in your chosen mechanism. (6 pts - 1 pt for chosen mechanism, 1 pt for each rate law, 2 pts for intermediate(s)/catalyst(s))

Acylinder is filled with 2.00 moles of nitrogen, 3.00 moles of argon and 5.00 moles of helium. if the gas mixture is at stp, what is the partial pressure of the argon

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
