Which of the following statements is CORRECT for a reaction at an equilibrium?
The rate of forward and reverse reactions are equal.
The final concentrations of product and reactant are equal.
The initial concentrations of product and reactant are equal.
The rate constant of the forward and reverse reactions are equal.
For the graph, choose the CORRECT statement.
The rate of reaction slowly increase
The systems never reach equilibrium
At equilibrium, more NO2 is present than N2O4.
At start of reaction, only NO2 was present.
For the reaction, choose the CORRECT equilibrium constant, Kc.
From the reaction, choose the CORRECT equilibrium constant, Kp.
At elevated temperatures ammonium carbonate, NH2COONH4, is in equilibrium with NH3 and CO2 according to the equation;
NH2COONH4(s) ↔ 2 NH3(g) + CO2(g)
What is the equilibrium expression for this reaction?
K = 2 [NH3][CO2]
[NH2COONH4]
K = [NH3]2[CO2]
[NH2COONH4]
K = 2 [NH3][CO2]
K = [NH3]2[CO2]
CO2(g) + H2(g) ↔ CO(g) + H2O(l)
Which of the following is true for a chemical reaction at equilibrium?
Only the forward reaction stops
Both the forward and reverse reactions stop
The reaction quotient value is equal to equilibrium constant
The rate constants for the forward and reverse reactions are equal
Which of the following are equal for a chemical system at equilibrium?
The concentrations of reactant and products are equal
The rate constants for the forward and reverse reactions are equal
The time that a particular atom or molecule spends as a reactant and product are equal
The rate of the forward and reverse reaction as the equilibrium has achieved
What is the Kc expression for the reaction below:
SOCl2(g) + H2O(g) ⇌ SO2(g) + 2HCl(g)
[SOCl2][H2O][SO2][2HCl]
[SOCl2][H2O][SO2][HCl]2
[SO2][2HCl][SOCl2][H2O]
[[SO2][2HCl][SOCl2][H2O]
SO2 (g) + NO2 (g) <=> SO3 (g) + NO (g)
had reached a state of equilibrium, was found to contain
0.40 mol L-1 SO3 , and 0.30 mol L-1 NO,
0.15 mol L-1NO2 , and 0.20 mol L-1 SO2.
Calculate the equilibrium constant for this reaction.
