Prac 18 – Reaction Rate of Notongooglenium – Angus Dally
Research Question:
How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)?
Aim
The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol).
Introduction
Notongooglenium
Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its placement on the periodic table between Chromium (24) and Manganese (25), it is believed to have a similar atomic and electronic structure to these two elements, and hence similar chemical properties. This means that Chromium or Manganese can be used …show more content…
The positively charged manganese ions, when near the C=C bond, will pull the negatively charged region of the electrons in the bond towards itself, weakening them. This means that when there is a collision between H2O and this C=C bond, in the presence of this catalyst, the bond will break more easily, which increases the amount of collisions with a high enough energy to cause a reaction, and hence an increase in the reaction rate. Since a product of this reaction is oxygen gas, it will bubble up through the liquid, into the syringe. The amount of oxygen gas present in the syringe at a certain point of time is proportional the rate of reaction (assuming the reaction is not complete), and so can be used as an indicator of the rate of reaction.
Variables
Independent: Amount of manganese oxide catalyst (g)
Dependent: Amount of oxygen gas evolved (dm3)
Controlled: Pressure, concentration of vinyl alcohol, reaction time
Uncontrolled: Temperature (reaction is exothermic), evaporation of water, dissolved oxygen gas.
Hypothesis
It is hypothesised that the rate of reaction will increase with the addition of the manganese oxide catalyst, as it will provide an alternate reaction mechanism with a lower activation energy.

In the event of eye exposure, remove contact lenses and wash eye for 15 minutes at an eye wash station, and get medical attention if irritation occurs. 3
If inhaled in large quantities, move to fresh air, and get medical attention. 3
If ingested, do not induce vomiting, and get medication if symptoms develop. 3
Manganese Oxide:
Chemical Risks:
Hazardous in the event of ingestion or inhalation, acts as an irritant in case of skin or eye contact.2
Non-flammable.2
Disposal:
Can be disposed of in bin if a solid, or poured down the sink if in an aqueous solution.2
Emergency treatment:
In the event of exposure to skin, wash with soap and water, and get medical attention if irritation develops. 2
In the event of eye exposure, remove contact lenses and wash eye for 15 minutes at an eye wash station, and get medical attention. 2
If inhaled in large quantities, move to fresh air, and get medical attention.
