A reaction in which A,B ,C and react to form products is first order in A, second order in B, and zero order in C. What is the overall order of the reaction? By what factor does the reaction rate change if A is doubled (and the other reactant concentrations are held constant)? By what factor does the reaction rate change if C is doubled (and the other reactant concentrations are held constant)? By what factor does the reaction rate change if the concentrations of all three reactants are doubled?
Suppose your thermometer read consistently 1.0 o C lowered throughout both parts in the colligative properties lab. What effect would that have on your experimental value for the molar mass of your unknown solute?

How are the opposing pathways of glycolysis and gluconeogenesis prevented from extensive futile cycling? a) The catabolic and anabolic pathways do not take place in the same part of the cell
Determine the percent yield if a student decomposes H 2 O to Form hydrogen (H) and oxygen(O). If the student starts with 34.7 grams of H2O and collects 20.0 grams of oxygen,
Consider the four equations of states(EOS) below describing PVT behavior of gases. Let a and b be constants. EOSI : PV = RT EOSII: (P-a)V = RT EOSIII: P(V-b) = RT EOSIV: P = RT/(V-b) - a/V (a) Prove for EOSI that both U and H are functions of T on..
