1.6 Chemical Equlibira

Question 1

Explain what effect increasing the temperature would have on the value of Kc, and the concentration on the products.

Answer 1

Kc decreases
Equilibrium shift to the left
Concentration of products decreases

Question 2

State and explain the effect, if any, on the value of Kc if a catalyst was added to the reaction

Answer 2

No effect on Kc
Catalysts speeds up the forward and backwards reaction equally

Question 3

predict the qualitative effects of changes of temperature on the value of K c

Answer 3

When the position of equilibrium is altered due to a temperature shift:

A decrease in the amount of product at equilibrium causes Kc to decrease.
An increase in the amount of product at equilibrium causes Kc to increase.
