According to Le Chatelier principle, equilibrium will shift in the forward direction. is 3.0 × 10–25 J, calculate its wavelength. (ii) 1 mole of carbon is burnt in 16 g of dioxygen. (iii) 100 atoms of A + 100 molecules of B. Calculate the dissociation constant of acetic acid if λ0m for acetic acid is 390 S cm2 mol-1. The acid dissociation constant K_a of acetic add (HCH_3CO_2) is 1.8 times 10^-5. How would you convert the following compounds into benzene? K a, the acid dissociation constant or acid ionisation constant, is an equilibrium constant that refers to the dissociation, or ionisation, of an acid. According to Le Chatelier’s principle, equilibrium will shift in the backward direction. If its K.E. O and one mole of CO are taken in a 10 L vessel and heated to 725K. Determine the empirical formula of an oxide of iron which has 69.9% iron and 30.1% dioxygen by mass. Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression? D. 3.0 x 10 4. equilibrium composition will not be disturbed but equilibrium will be attained equally.However, in the presence of a catalyst, the equilibrium would be attained quickly. As will increase with the increase of temperature. The equilibrium constant for the equilibrium, CN-+ CH 3 COOH and HCN + CH 3 COO-would be. Calculate the degree of dissociation of acetic acid in its 0.05 M solution. Pressure of 1 g of an ideal gas A at 27 °C is found to be 2 bar. The ionization constant of acetic acid is 1.74 x 10-5.

What will be the minimum pressure required to compress 500 dm3 of air at 1 bar to 200 dm3 at 30°C? (iii) As given reaction is endothermic, on increasing the temperature, Af will increase. The rate of condensation decreases initially because vapour pressure per unit volume decreases. Round your answer to 1 decimal place. The solution to this paradox is simply to ignore Reaction 1 and treat the problem as though all A-comes from Reaction 2.
