35 Solution: Pressure comes from the collisions of all gas molecules. p total p H 2 p CO p CH 3 OH This is a limiting reagent problem because amounts of 2 reactants are given. CO g 2H 2 g CH 3 OH a. Calculate moles of product expected assuming CO is the limiting reagent. . 23.0 grams 28.01 grams/mole 1 mole CH 3 OH 1molCO 0.82114 mole CH 3 OH b. Calculate moles of product expected assuming H 2 is the limiting reagent. 4.0 grams 2.02 grams/mole 1 mole CH 3 OH 2 mol H 2 0.99010 mole CH 3 OH c. The actual amount of product produced will be the smaller amount of product calculated in steps 1 and 2 or 0.82114 mole CH 3 OH From this we see that CO is the limiting reagent. d. The amount of hydrogen left over will be the initial amount minus what reacts. To find out how much
