Interpret Data and Determine Rate Law of Gas Phase Reaction


You’ve been in the research lab for the past 3 months. Dr. Bowman said he would let you out of the lab once you determined the rate law for the gas phase reaction
W + X → Y + Z

Twenty-two boxes of Ritz crackers and 37 tins of tuna fish later, the following table summarizes your work

What is the best choice for a rate law that fits the data?

a)    –rW = k1PWPXPYPZ
b)    –rW = k1PWPY2/(1+k2PX)
c)    –rW = k1PWPX/(1+k2PY)
d)    –rW = k1PWPX2/(1+k2PY)
e)    –rW = k1PWPX2/(1+k2PY)
f)    –rW = k1PWPX2/(1+k2PX)
g)    –rW = 7


The short answer question belongs to Chemical Engineering and it is about determining the rate law of gas phase reaction. The answer is dependent on the data given in the table.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
