Question
Which of the following are true statements about equilibrium systems?
True/False For the following reaction at equilibrium:
2 H2(g) + O2(g) 2 H2O(g)
the equilibrium will shift to the left if the volume is doubled.
True/False For the following reaction at equilibrium:
H2(g) + F2(g) 2HF(g)
removing H2 will decrease the amount of F2 present once equilibrium is reestablished.
True/False For the following reaction at equilibrium:
CaCO3(s) CaO(s) + CO2(g)
adding more CaCO3 will shift the equilibrium to the right.
True/False Increasing the temperature of an exothermic reaction shifts the equilibrium position to the right.
True/False For the following reaction at equilibrium:
CaCO3(s) CaO(s) + CO2(g)
increasing the total pressure by adding Ar(g) will shift the equilibrium to the right.
Explanation / Answer
True/False For the following reaction at equilibrium:
2 H2(g) + O2(g) 2 H2O(g)
the equilibrium will shift to the left if the volume is doubled. IF we double Volume we decrease P. If we decrease P we favour more mol formation. Then the fhist goes to LEFT. This is TRUe
True/False For the following reaction at equilibrium:
H2(g) + F2(g) 2HF(g)
removing H2 will decrease the amount of F2 present once equilibrium is reestablished. FAlse, since the shift will shit toward reactants to form H2 and F2
True/False For the following reaction at equilibrium:
CaCO3(s) CaO(s) + CO2(g)
adding more CaCO3 will shift the equilibrium to the right. true, since increase in reagents increases production
True/False Increasing the temperature of an exothermic reaction shifts the equilibrium position to the right.
True/False For the following reaction at equilibrium:
CaCO3(s) CaO(s) + CO2(g)
increasing the total pressure by adding Ar(g) will shift the equilibrium to the right. false, will shift it to the left since there ar eno mole formation.
