Question

If Q$/{\text{K}}_{\text{c}}>1$ , then the reaction proceeds left to right but if Q$/{\text{K}}_{\text{c}}>1$, then the reaction proceeds right to left.
If true enter 1, false enter 0.

Answer 1

Hint:Check for the value of reaction quotient Q. If it is less than ${\text{K}}_{\text{c}}$, then the reaction proceeds in the forward direction.

Complete answer:
When Q/${\text{K}}_{\text{c}}$ is less than one, it means value of ${\text{K}}_{\text{c}}$ is more than Q which means the concentration of products is lower than the equilibrium concentration. So, the equilibrium will shift in the forward direction i.e. from left to right.
 And when by Q$/{\text{K}}_{\text{c}}>1$,, it means the value of ${\text{K}}_{\text{c}}$ is less than Q so that concentration of products is more than the equilibrium concentration. So, to attain equilibrium the reaction will proceed in a backward direction that is from right to left.

So, the given statement is correct. Therefore, enter 1.

Additional information: The reaction quotient (Q) measures the relative amount of products and reactants present during a reaction at a particular point in time. The reaction quotient helps in figuring out in which direction a reaction is likely to proceed, given either the pressure or the concentration of the reactants and products.
 Q can be used to determine in which direction a reaction will shift to reach equilibrium if ${\text{K}}_{\text{c}}>1$ the reaction will proceed in the reverse direction, i.e. converting products into reactants. If Q = ${\text{K}}_{\text{c}}$ then the system is already at equilibrium.
 The value of ${\text{K}}_{\text{c}}$,the equilibrium constant may depend on the temperature but not on the amount of the compound and nor on the pressure. The value of Q depends only on the partial pressure and the concentrations. If there is a change in either Q or ${\text{K}}_{\text{c}}$ the reaction will go in the direction which will re-establish the condition of the reaction quotient being equal to equilibrium constant.

Note:
Study the concept of reaction quotient, the equilibrium constant, the factors affecting the way in which the reaction proceeds, the reaction between reaction quotient and equilibrium constant and their interdependence, the change in the concentration of reactants and products based on the proceedings of reaction as given in the information above.
