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

Accepted Answer

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.
