1. The absorbance of an iron thiocyanate solution containing0.00500 mg Fe/mL was reported as 0.4900 at 540 nm.
A) Calculate the specific absorptivity, including units, of iron thiocyanate on the assumption that a 1.00 cm cuvette was used.
B) What will be the absorbance if (1) the solution is dilutedto twice its original volume and (2) the solution is placed into a5.00 cm cuvette?
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of Br- is doubled? Just put in the number as a whole number or fraction.
The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions.
In the reaction below, 2.41 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) 2 HBr(g) Given that Kc = 52.2, calculate the equilibrium pressure of H2.
The decomposition of hydrogen peroxide is catalyzed by iodide ion. The catalyzed reaction is thought to proceed by a two mechanism reaction
