“If a stress is applied to a system in dynamic equilibrium, the system changes in a way that relieves the stress”.
Le Chatelier's principle
Hund’s principle
Avogadro's principle
When the rates of the forward and reverse reactions are equal, the reaction has reached a state of balance called chemical equilibrium.
True
False
True or False. When equilibrium is reached in a reaction, both the forward reaction and the reverse reaction stop.
True
False
The following reaction is allowed to reach equilibrium:
2H2 (g) + CO (g) <---> CH3OH (g) ΔHo = -91 kJ/mol
Which way would the reaction go if Helium is added to the container?
To the left (towards reactant)
To the right (towards the product)
There would be no shift
The following reaction is allowed to reach equilibrium:
2H2 (g) + CO (g) <---> CH3OH (g) ; ΔHo = -91 kJ/mol
Which way would the reaction shift if there was an increase in temperature to the reactor vessel?
To the right (towards product)
To the left (towards reactant)
There would be no shift in reaction.
The following reaction is allowed to reach equilibrium:
2H2 (g) + CO (g) <---> CH3OH (g) ; ΔHo = -91 kJ/mol
Which way would the reaction shift if additional CO was added to the vessel?
To the right (towards the products)
To the left (towards the reactants)
There would be no shift in reaction
The following reaction is allowed to reach equilibrium:
KOH (aq) <---> K+ (aq) + OH- (aq)
What would happen to the reaction if the pressure in the vessel increased
Shift to the right (towards products)
Shift to the left (towards reactants)
There would be no shift.
The following reaction is allowed to reach equilibrium:
2H2 (g) + CO (g) <---> CH3OH (g) ; ΔHo = -91 kJ/mol
Which way would the reaction shift if the volume of the vessel was doubled?
To the right (towards product)
To the left (towards reactant)
There would be no shift in reaction.
What is still confusing? How can I help?
