F. M. Miller and M. L. Adams had measure the kinetics for the alkaline hydrolysis of p-nitrosodiumdimethylaniline (NSA). This is a second order reaction, first order with respect the NSA and first order with respect to hydroxide ion. Use the data below to calculate the rate constant. [NSA] [OH-] t(s) mol/liter mol/liter 0 0.0500 0.199 135 0.0413 0.190 380 0.0365 0.186 610 0.0325 0.182 945 0.0282 0.177 1880 0.0187 0.168

What is the hydronium-ion concentration of a 4.07 10-4 M solution of p-bromobenzoic acid, BrC6H4COOH, for which Ka = 1.00 10-4
A compound A (C22H27NO) is insoluble in acid and base but reacts with concentrated aqueous HCl and heat to give a clear aqueous solution from which, on cooling, benzoic acid precipitates.
What are the units of the universal gas constant R? When can a real gas behave as an ideal gas? Are these conditions met in this experiment?
The rate law for the reaction, 2NO(g) + O2(g) -- 2NO2(g), is found to be: rate of reaction=k[NO]2[O2]2 (PLEASE note that the 2's after the concentrations are powers, so we have NO to the power of 2 and O2 to the power of
