Quiz | Chemical Equilibrium
Which of the following statements about the equilibrium constant is correct?
It changes with changes in the temperature
It changes by the addition of a catalyst
It always remains the same at different reaction conditions
It increases if the concentration of one of the reactants or products is increased
Which of the following statements is correct?
At the equilibrium, sum of [reactant] = sum of [product]
At the equilibrium the forward and reverse reactions still occur
A chemical equilibrium can be attained only starting from a mixture
Chemical equilibrium is a static equilibrium, [reactant] = constant and [product] = constant
What is the equilibrium constant expression KC of the reaction: N2 (g) + 3 H2 (g) 2 NH3 (g)?
What is the equilibrium constant expression KC of the reaction: 2 ICl (s) I2 (s) + Cl2 (g)?
How can we increase the total amount of produced Cl2 during the reaction: 2 ICl (s) I2 (s) + Cl2 (g)?
By adding more ICl
By increasing the pressure
By removing the Cl2 as it is formed
By decreasing the volume of the container
What happens when the reaction quotient QC is less than the equilibrium constant K?
The reaction will move to the left
The reaction will move to the right
It depends on whether the reaction is endothermic or exothermic
It depends on the reaction conditions
