In the two gaseous reactions (i) and (ii) at 250o C.
the equilibrium constants K1 and K2 are related as
The rate constants for forward and backward reaction of hydrolysis of ester are 1.1 × 10-2 and 1.5 × 10-3 per minute. Equilibrium constant for the reaction
CH3 COOC2H5+H+ CH3COOH + C2H5OH is
4.33
5.33
6.33
7.33
For a reversible reaction, if the concentration of the reactants are doubled, the equilibrium constant will be
one-fourth
halved
doubled
the same
According to Le-Chatlier's principle, adding heat to a solid liquid equilibrium will cause the
temperature to increase
temperature to decrease
amount of liquid to decrease
amount of solid to decrease
If the concentration of OH- ions in the reaction is decreased by times, then equilibrium concentration of Fe3+ will increase by
8 times
16 times
64 times
4 times
Reaction In equilibrium condition, pressure of O2 depends on
increased mass of BaO2
increased mass of BaO
increased temperature of equilbrium
increased mass of BaO2 and BaO both
