- Advanced Level Chemistry (Salters') - Paper 3 mock.
ROBERT TAYLOR U6JW.
A Catalyst is a substance that alters the rate of a reaction. The catalyst
remains unchanged at the end of the reaction. The process is called catalysis.
In this report I aim going to.... Part 2 of Paper
....xyl groups (R-OH) where the O-H bond is broken to produce R-O-
and H+. When the reactant receives protons from an acid it undergoes a
conformational change, (change in shape and configuration), and becomes a
reactive intermediate. The intermediate can then either become an isomer by
returning a proton to the catalyst, or it may undergo a further reaction and
form a completely new molecule.
Up until the mid - 1960's silica-alumina gels were used to catalyse the cracking
of hydrocarbons. This for.... |
