Method/Apparatus/Procedure:
The apparatus consisted of an absorber, 10-cm3 in volume, and a complex system using electrical contacts in a tube for maintaining a constant gas supply pressure in the absorber. The contacts were used to start and stop a gear pump which pumped silicone oil as an 'inert' medium to displace gas from a gas storage vessel. The change in volume of silicone oil utilized was read on a burette and was considered to represent the volume of gas used. The absorber initially contained 3-5 cm3 of solvent confined in a thin-walled glass ampoule. The chamber was pressurized with gas and to initiate the experiment the ampoule was broken using a stainless steel ball.
Source and Purity of Materials:
- Ethene purity was 99.8%.
- Acetone was reagent grade with water content small than 0.5%.
