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

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

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

A system at equilibrium is exothermic in the forward direction. Which change would increase the equilibrium yield of products?

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:

In an experiment the equilibrium constant Kp for a gas reaction is measured at two temperatures and is found to increase with temperature. From this you can conclude the forward reaction is:

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

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:

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

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

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

For the gas equilibrium 2NO2(g) ? N2O4(g), the forward reaction is exothermic. If the temperature is increased and pressure held constant, the equilibrium colour changes from brown to:
