The keq of a reaction is 4 x 10-7 at equilibrium, the reactants are favored.
if forward and backward rates balance in any reaction, then the reaction is at equilibrium.
k is the equilibrium constant and it shows the relationship between products and reactants at equilibrium.

if keq is smaller than 1, the reactants are more at equilibrium.

so here keq is less than 1, it means reactants will be favored.

Ibelieve it's celsius. hope this .
