The Effect Of Temperature Changes On Equilibrium (ht Only) (GCSE Chemistry)

Which statement about Le Chatelier’s principle and temperature is correct?

For the equilibrium A ? B, a decrease in temperature causes the position to move to the left. The forward reaction is therefore:

An endothermic forward reaction has activation energy Ea,f and reverse Ea,r. Adding heat (raising temperature) generally:

When a reaction is exothermic in the forward direction, which of these changes will increase K (equilibrium constant) for the forward reaction?

A student observes that when temperature increases the colour of an equilibrium mixture becomes more intense and the forward reaction is known to be exothermic. The correct interpretation is:

Which change will not affect the equilibrium position but will increase how fast equilibrium is reached?

Consider the reaction N2(g) + 3H2(g) ? 2NH3(g), which is exothermic forward. Increasing temperature in the Haber process will:

For the heterogeneous equilibrium CaCO3(s) ? CaO(s) + CO2(g), increasing temperature will:

Which set of conditions would be best to increase the yield of a product when the forward reaction is exothermic and produces fewer gas molecules than the reactants?

At constant temperature, adding a catalyst to an equilibrium system will:

Which practical change in an industrial exothermic equilibrium reactor would increase product yield without changing temperature?
