Two well-known gas phase reactions take place in the dehydration of ethane: C2H6  C2H4 + H2 (a)

C2H6 + H2  2CH4 (b)

Given the product distribution measured in the gas phase reaction of C2H6 as follows:

C2H6 27%

C2H4 33%

H2 13%

CH4 27%

a. What species was the limiting reactant?

b. What species was the excess reactant?

c. What was the conversion of C2H6 to CH4?

d. What was the degree of completion of the reaction?

e. What was the selectivity of C2H4 relative to CH4?

f. What was the yield of C2H4 expressed in kilogram moles of C2H4 produced per kilogram mole of C2H6?

g. What was the extent of reaction of C2H6?
