How do perturbations to a system affect the equilibrium position of a reaction?

If a perturbation is applied to a system in dynamic equilbirium, the position of equilbirium will shift to favour the reaction which minimises the effect of the perturbation. If the forward reaction is exoth...

Why do acids have low pHs and alkaline solutions have high pHs?

The pH scale is a measure of how many H + ions there are in a solution. The higher the concentration of H + , the lower the pH and the more acidic the solution is. For example, for HCl, dissociation can occu...

What is the effect of increasing the temperature on the rate of reaction?

As the temperature has increased the particles have more kinetic energy which causes them to move more quickly so there are more collisions per unit time. Also, due to their increased kinetic energy, more pa...
