PPT-Solution Analyze We are given the concentrations of a reactant at various

times during a reaction and asked to determine whether the reaction is first or second order Plan We can plot lnNO 2 and 1NO 2 against time If one plot or the other . AP . Chem. Mr. Nelson. The Concept of Equilibrium. The term . reversible reaction . is used to describe reactions that can go in either the forward or the reverse direction.

Consider the balanced equation for the production of ammonia:. N. 2. . 3. H. 2. .  . 2. NH. 3 . If you have 2 moles of nitrogen and 3 moles of hydrogen, which reactant will be used up?. How much ammonia will you be able to make?. LG: I can perform concentration calculations involving units commonly used in consumer products. Percent Concentration. Many consumer products report the percent of solute relative to the total amount of solution; these concentrations may involve weights and volumes. If it takes 500 bricks and 1000 boards to make a house, how many houses can you make from 1600 bricks and 2000 boards?. 2 houses, there are enough bricks for 3.2 houses. but only boards for 2 with our plans (reaction).. 11-. 1. Activity: Precipitation Reactions. When a solution of lead(II) nitrate is mixed with a solution of potassium chromate, a yellow precipitate forms according to the equation:. Pb(NO. 3. ). 2. (.
