The solvent dischloromethane ( CH 2 Cl 2 , molar mass 84 .93 g/mol ) can be prepared by reaction of methan ( CH 4 , molar mass 16 .04 g/mol ) with Cl 2 (molar mass 70.90 g/mol), according to the balanced equation, CH 4 + 2Cl 2 → CH 2 Cl 2 +2HCl . If 5.00 g of methane and 15.0 g of Cl 2 are used, how many moles of each reactant are used? What is the limiting reactant? How many moles of product are formed? How many grams of product are formed? If 5.6 g of product are formed, what is the percent yield of the reaction?

Zeroth Order Reaction
In a certain experiment the decomposition of hydrogen iodide on finely divided gold is zeroth order with respect to HI.
2HI(g) Au H2(g) + 12(9)
Rate =
-d[HI]/dt k = 2.00x104 mol L-1 s-1
If the experiment has an initial HI concentration of 0.460 mol/L, what is the concentration of HI after 28.0 minutes?
