For a reversible reaction,if the concentration of the reactants is reduced to half,the equilibrium constant will be.........

For the following reaction,
$C_{12}H_{22}O_{11(aq)} + H_2O_{(l)} \rightleftharpoons C_6H_{12}O_{6(aq)} + C_6H_{12}O_{6(aq)}$
Which of the following characteristics is not affected by the addition of a catalyst?

One mole of $A_{(g)}$ is heated to $200^{\circ} C$ in a one litre closed flask,until the following equilibrium is reached:
$A_{(g)} \rightleftharpoons B_{(g)}$
The rate of forward reaction at equilibrium is $0.02 \ mol \ L^{-1} \ min^{-1}$. What is the rate (in $mol \ L^{-1} \ min^{-1}$) of the backward reaction at equilibrium?

Explain equilibrium in a saturated solution and its dynamic nature.

$A$ reversible reaction $H_2 + Cl_2 \rightleftharpoons 2HCl$ is carried out in a $1 \ L$ flask. If the same reaction is carried out in a $2 \ L$ flask,the equilibrium constant will be

$A$ chemical reaction is at equilibrium when
