3.17 Equilibrium Flashcards
Explain why increasing the temperature in the Deacon process results in less chlorine being produced.
State what is meant by the term dynamic equilibrium.
The ammonia produced is continuously removed. Explain how this will affect the production of ammonia.
Explain fully the effect of decreasing the reaction temperature on the yield of ammonia.
What is the effect of a catalyst.
Draw a graph on the axes below to show how the yield of carbon dioxide would vary with increasing temperature. (Exothermic)
Explain fully why using a concentrated sodium chloride solution encourages production of sodium hydrogen carbonate as a solid
By adding more brine it increases sodium ion concentration hence equilibrium shifts to the right. So, the rate of the forward reaction is increased.
State the effect of increasing temperature on the position of equilibrium.
Equilibrium will shift to the left
State why changing the pressure has no effect on this equilibrium reaction.
There are the same number of moles on each side of the equation.
Explain clearly why mixing the bleach with an acid would shift the equilibrium to the right, resulting in the release of chlorine gas from the bleach cleaner.
Adding an acid increases H+ ions, the rate of forward is increased.
