Chemistry 12: Reaction Kinetics Review 1. Looking at the expressions for reaction rate‚ write expressions with which you could express rates for the following reactions. (Hint: look at what happens to reactants and products.) Recall that solid or liquids can lose or gain mass‚ gases can lose or gain volume and aqueous solutions can increase or decrease in concentration. ("a" is done as an example.) a) Mg(s) + 2HCl(aq) H2(g) + MgCl2(aq) reaction rate = mass of Mg consumed unit time b) c) or

Abstract This experiment is to study and measure the enzyme activity of β-galactosidase in the different concentrations of o-Nitrophenylgalactoside (ONPG) using a spectrophotometer. The spectrophotometer was also set at 420nm‚ a wavelength which is best for recording the absorbance values for the experiment. From the results‚ 0.9mM ONPG solution has the highest absorbance and 0.1mM ONPG solution has the least. Also‚ 0.5mM ONPG solution has the highest rate of enzyme activity and it is the most efficient

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each
