1. For the reaction:
N2 + 3H2 → 2NH3
Calculate the number of grams of NH3 formed when2.28 mol of N2 is treated with 1.51 molH2
2. You dissolve0.275 g of silver nitrate into 0.541 L of distilled water. You thentake 10.5 ml of that dilution and dilute to make a total volume of506.0 mL. What is the concentration in your second solution?
3. The oxidation of ammonia produces nitric oxide and wateraccording to the following unbalanced equation. What massof nitric oxide can be made from the reaction of 8.00 gNH3 with 17.0 g O2?
NH3(g) + O2(g) →→ NO(g) +H2O(g)
Answer to 3 significant figures.
4. For the second-order reaction below, the rate constantof the reaction unknown with unitsof M–1s–1. If after213.6 s the concentration of A goes from 9.24 M to 0.07 M, what isthe rate constant for this reaction?Do not include units with your answer.
2A → B
5.
When the reaction A → B + C is studied, a plot ofln[A]t vs. time gives a straight line witha negative slope. What is the order of the reaction?
Select one:
a.zero
b.first
c.second
d.third
e.More information is needed to determine the order.
6. For the second-order reaction below, the rate constantof the reaction is 1.3 x10–3 M–1s–1. How long (inseconds) is required to decrease the concentration of A from 8.93 Mto 0.02 M?Be sure to include units (as the SI abbreviation) in youranswer.
