When the temperature is higher, each molecule is moving faster. This means that in a given time period, more collisions will occur between molecules, leading to a reaction. Also, the molecules will have a greater kinetic energy, so they will be more likely to collide with higher energy than the activation energy, which is required for them to react.

When the temperature is higher, the particles of the reactants will have more energy, so they will move more quickly. This means they will collide more, and the collisions are successful more often - the rate of reaction is increased.

Hope that helps!

Oh, didn't come up in my notifications.

Maybe you can answer my other unanswered threads question:

How does gas chromatography work?

and

What is electroplating? and what is it used for?

Not sure my AS brain can remember this GCSE stuff
but electroplating is when you coat an object with another metal, maybe for a nice finish? or maybe to protect it so it lasts longer?

If this AQA here is what you're expected to know from the spec for gas chromatography:
  • different substances, carried by a gas, travelthrough a column packed with a solid material atdifferent speeds, so that they become separated
  • the number of peaks on the output of a gaschromatograph shows the number of compoundspresent
  • the position of the peaks on the output indicatesthe retention time
  • a mass spectrometer can identify substances veryquickly and accurately and can detect very smallquantities.

With electroplating it's basically what Big white said. I think you're also expected to know the half equations for electrolysis, but not absolutely sure.
