Title: Investigating How Increasing Volume of AgNO 3 Catalyst Influence the log of Pre-exponential Factor in
the Alcohol Oxidation Reaction

Research Question : How do different volumes of 0.1 M AgNO 3 catalyst (0.200mL, 0.400mL, 0.600mL,
0.800mL, 1.000mL) affect the log of pre-exponential factor of oxidation reaction among 2.69M CH 3 CH 2 OH,
0.02M K 2 Cr 2 O 7 and 4M H 2 SO 4 , as measured by the change in blue light absorbance (439.6nm) through
spectrophotometer and calculated by Arrhenius equation?

Title:​ Investigating How Increasing Volume of AgNO​3 Catalyst Influence the log of Pre-exponentialFactorin the Alcohol Oxidation Reaction

Research Question​: How do different volumes of 0.1 M AgNO​3 catalyst (0.200mL, 0.400mL, 0.600mL, 0.800mL, 1.000mL) affect the log of pre-exponential factor of oxidation reaction among 2.69M CH​3​CH​2​OH, 0.02M K​2​Cr​2​O​7 and 4M H​2​SO​4​, as measured by the change in blue light absorbance (439.6nm) through spectrophotometer and calculated by Arrhenius equation?

Background Information​: The chemistry is a basis of many multidisciplinary fields such as criminology and psychology. As a student in the humanities field learning HL chemistry, I was interested in looking at the
application of variouschemicaltheoriesandreactionsinreallife.Oneexampleisthebreathalyzerreaction.The
breathalyzer is a device that measures the blood alcohol content in a breath sample. Theapplicationofalcohol
oxidation reaction and the spectrophotometry allows the measurement of amount of alcohol in one’s breath,
helping the law enforcement…
