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

Which of the following is a correct industrial strategy when an equilibrium reaction is exothermic and the desired product has fewer gas moles than the reactants?

Which of the following changes will alter the value of the equilibrium constant K for a given reaction?

A student measures equilibrium concentrations at two temperatures and finds K1 > K2 where K1 is at lower temperature. The forward reaction must be:

If an equilibrium constant Kc for the reaction A + B ? C + D decreases when temperature is increased, the forward reaction is:

When the temperature is increased for a reversible reaction that is exothermic in the forward direction, the equilibrium position will shift to:

For a reversible reaction that is endothermic in the forward direction, raising the temperature will:

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

Which of the following statements about the effect of temperature on an equilibrium constant K is correct?

Which graph best shows the effect of a catalyst on a reaction energy profile (activation energy Ea and overall ?H unchanged)?

At constant temperature, for the reaction P ? Q, the measured K decreases when a small amount of Q is removed and the new equilibrium is established. This implies:

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:
