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

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

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

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

For the reversible reaction A(g) ? B(g), ?H° forward = -120 kJ. If the temperature is reduced, the equilibrium constant K will:

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

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

A reversible gas reaction has ?H° = +85 kJ (endothermic forward). If the temperature is increased the equilibrium will:

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

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:

For the equilibrium 2A(g) ? B(g) + C(g) with ?H° forward = +60 kJ (endothermic), increasing temperature will:

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