If the equilibrium constant is much greater than one (K >> 1) then

Equilibrium lies to the right (products are favored)

Equilibrium is not established.

Equilibrium lies to the left (reactants are favored)

Neither products or reactants are favored.

Hydrazine is produced from it elements as follow: N2 + 2H 2 => N 2 H 4 H=+ve kjmol -1

Increase in the temperature of the system

Decrease in the pressure of the system

Increase in the value of the reaction vessel

What is the equilibrium expression for: Fe 3 O 4 (s) + 4H 2 (g) <--> 3Fe(s) + 4H 2 O(g)

([Fe] 3 [H 2 O] 4 ) / ([Fe 3 O 4 ][H 2 ] 4 )

([Fe 3 O 4 ][H 2 ] 4 )/ ([Fe] 3 [H 2 O] 4 )

([Fe][H 2 O]) / ([Fe 3 O 4 ][H 2 ])

There are more products than reactants when the reaction reached equilibrium.

There are more reactant than products when the reaction reached equilibrium.

The amount of reactants is equal to the amount of products.

There are more reactant than products when the reaction reached equilibrium.

There are more products than reactants when the reaction reached equilibrium.

The amount of reactants is equal to the amount of products.

At elevated temperatures ammonium carbonate, NH 2 COONH 4 , is in equilibrium with NH 3 and CO 2 according to the equation; NH 2 COONH 4 ( s ) ↔ 2 NH 3 ( g ) + CO 2 ( g ) What is the equilibrium expression for this reaction?

K = 2 [NH 3 ][CO 2 ]/[NH 2 COONH 4 ]

K = [NH 3 ] 2 [CO 2 ]/[NH 2 COONH 4 ]
