Answer to Question #213047 in General Chemistry for Alaa Aboukhadra

Question

For a reaction system at chemical equilibrium

the reaction is always shifted to the right if the concentration of right side species increases

the composition at equilibrium is not affected by catalysts

 

catalysts only affect speed to speed to get to equilibrium

the reaction is always shifted to the left if the concentration of right side species decreases

If Q is greater than K the reaction will shift to the right

if Q is greater than K nothing will happen

the composition at equilibrium is affected by catalysts

If Q is greater than K the reaction will shift to the left

the reaction is always shifted to the left if the concentration of right side species increases

the reaction is always shifted to the right if the concentration of right side species decreases

Answer 1

Chemical equilibrium is a state of a chemical, reversible process in which the rate of a direct reaction is equal to the rate of the reverse reaction. For a system in chemical equilibrium, the concentrations of reagents, temperature and other parameters of the system do not change with time.
