The elements of Group 7, the halogens, have many important uses. Fluorine is used to make sulfur hexafluoride, $$\(\mathrm{SF}_{6}\)$$, a gas which is used as an insulator in electrical equipment. Chlorine is used as a bleach and as a disinfectant in water treatment. Bromine is used to make organic chemicals that are used as fire retardants. lodine has been used in the catalyst in the manufacture of ethanoic acid. The industrial manufacture of ethanoic acid first used an iodine-based catalyst. Explain, with the aid of a labelled Maxwell-Boltzmann distribution, how a catalyst y38Y SIHIN1A1AM10N 00 increases the rate of a chemical reaction.

Answer:
An explanation that makes reference to the following points:
- \(y\)-axis label
and
x-axis label
- single distribution starting at the origin and approaching but not touching the x-axis
- catalyst provides (alternative route with)
lower activation energy / \(E_{\mathrm{a}}\)
- more particles/collisions have \(E \geq E_{\mathrm{a}}\) with catalyst
- \(y\)-axis label
and
x-axis label
- single distribution starting at the origin and approaching but not touching the x-axis
- catalyst provides (alternative route with)
lower activation energy / \(E_{\mathrm{a}}\)
- more particles/collisions have \(E \geq E_{\mathrm{a}}\) with catalyst
