I've been asked to talk about the reversible reaction between iron ions and thiocyanate ions. It says the colour of the reaction is orange at room temperature.
I have to say:
-the name of the solvent used to dissolve the ions in this reaction
- what the colour change would be if a colourless solution containing a high concentration of thiocyanate ions was added

It then goes on to ask
A water bath is set up at a temperature above room temperature.
When a test tube containing the orange equilibrium mixture is placed in the water
bath, the mixture becomes more yellow.
Explain what this shows about the energy change for the forward reaction.

I don't really understand any of these questions other than knowing its to do with le chateliers principle. Can someone please help me and explain them to me

The following page contains info on Le Chateliers principle.

https://www.science-revision.co.uk/L...principle.html

For the example you give you need to know whether the forward or reverse reaction is exo/endo thermic.

Adding an extra reactant or product - see the webpage it explain it, it uses different examples but the principle is exactly the same
