Balanced chemical equations illustrate the relationships between quantities of products and reactants. (SC09-GR.HS-S.1-GLE.3-EO.a,c,d) How are amounts of products and/or reactants calculated from a balanced chemical equation?

Reactants bind to the surface. (Increases A because 3-dimensional search is changed to 2-dimensional search.) Bonds in reactants are weakened. (Reactants are . destabilized.) Heterogenous catalyst differ from enzymes as follows: They are not dissolved. (This is an advantage because it is easy to separate the catalyst from products!)

Students may use a calculator for this part (55 minutes). Part B (40 minutes) is the three reactions question (predict the products of a reaction, balance, and answer a short question regarding the reaction) and the two theory questions. A laboratory question could be in either part A or B. NO calculator is allowed in part B. 2007 part B ...

The presence of products can alter results dramatically and lead to confusing results. We'll be talking initial reaction rates: Rate = k[NO2]n = Rate expression or rate law is the relation between reaction rate and the concentrations of reactants given by a mathematical equation. CONCENTRATION AND REACTION RATE:

A concentration cell involves a reaction having the same reactants as products, but with differing concentrations. In which direction is the reaction spontaneous? For concentration cells, E0 = 0 , n = 2. E = - (0.0257/ n)lnQ. E = -(0.0257) ln ( 0.5 x (0.5)2) / (2 x (0.1)2) E = -0.047v ...

Important note: These reactions will only occur if both reactants are soluble in water and only one product is soluble in water. 6) If an acid and a base combine, it’s an acid-base reaction. The products will be an ionic compound and water. On the next page are explanations of how this works in sample problems: 1) ____ Ag2SO4 + ____ NaNO3 (

Note that one reactant is in its elemental form; if a single replacement reaction is going to occur, the species NOT in its elemental form in the reactants (H+ in this case), will end up in its elemental form in the products (H2) and the species that IS in its elemental form (Zn) will end up ionized (Zn2+).
