4.18 Consider the following CO oxidation reactions:CO OH CO HCO O CO O,22 2+→ ++→ +kk12where k1 (cm3/ gmol-s) = 1.17 ⋅ 107T (K)1.35 exp[+3000 / RuT (K)], k2 (cm3/gmol-s) = 2.50 ⋅ 1012 exp[−200,000 / RuT (K)], and Ru = 8.315 J / gmol-K. Calculate and compare the characteristic times associated with these tworeactions for T = 2000 K and P = 1 atm. The CO mole fraction is 0.011 andthe OH and O2 mole fractions are 3.68 ⋅ 10−3 and 6.43 ⋅ 10−3, respectively.

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
