HideShow resource information
Q: Why does Kc have no units in expression 3?
A: There are the same number of moles on both sides of the equation, so the volumes cancel.
1 of 5
Q: Suggest why the reaction mixture was cooled rapidly?
A: To stop the reaction so that the equilibrium concentrations do not change
2 of 5
Q: What role does a catalyst have on the equilibrium reaction?
A: A catalyst increases the rate at which equilibrium is reached
3 of 5
Q: State and explain 2 benefits to the environment from the use of catalysts?
A: Less fuels is needed, Less raw materials are needed, Less natural resources are used because the reaction has a lower activation energy.
