The concept used to solve this problem is based on the equilibrium constant of a chemical reaction.
The value of the reaction quotient when a reaction reaches equilibrium is called equilibrium constant. It is the ratio of the concentrations of products and concentrations of reactants.
For a chemical reaction,
The equilibrium constant is written as follow.
Here and are concentrations of products. The concentrations of reactants are and.
For the reaction,
The equilibrium constant is written as follow.
The values of K, 0.2 and are less than one. Thus, at these values the reactant A is more than product B at equilibrium.
The values of K, 9000 and are more than one. Thus, at these values the product B is more than reactant A at equilibrium.
Ans:The values of K at which B is more than A are 9000 and .
For the reversible reaction which k values would indicate that there is more B than A...

Consider the reversible reaction A(g) = B(g) Which K values would indicate that there is more B than A at cquilibrium? K = 3 X 109 OK = 0.7 O K = 9 x 10-5 K = 5000
If the reaction quotient is greater than the equilibrium constant, which statement would be correct? A. If Q > K, then the reaction is at equilibrium. B. If Q > K, then the reaction needs to proceed towards the left to reach equilibrium. C. If Q > K, then the reaction needs to proceed towards the right to reach equilibrium. D. None of the above.
Expression for equilibrium constant (k) for reversible reaction H2 + I2 <-> 2HI is:
