2g of NaOH per 250mL of solution is added to a buffer solution of buffer capacity 0.2. Then the change in pH is
Find out the value of Kc for each of the following equilibrium from the value of Kp:
a. 2NOCl(g)⇔2NO(g)+Cl2(g),Kp=1.8×10−2 at 500K
b. CaCO3(s)⇔CaO(s)+CO2(g),Kp=167 at 1073K
The ionization constant of propanoic acid is 1.32×10−5. Calculate the degree of ionization of the acid in its 0.05 M solution and also its pH. What will be its degree of ionization if the solution is 0.01M in HCl ?
Dihydrogen gas used in Habers process is produced by reacting methane from natural gas with high temperature steam. The first stage of two stage reaction involves the formation of CO and H2. In second stage, CO formed in first stage is reacted with more steam in water gas shift reaction,
If a reaction vessel at 400oC is charged with an equimolar mixture of CO and steam such that PCO=PH2O=4.0bar, what will be the partial pressure of H2 at equilibrium? KP=0.1 at 400oC?
Calculate the degree of ionization of 0.05 M acetic acid if its PKa value is 4.74. How is the degree of dissociation affected when its solution also contains (a) 0.01M (b) 0.1M in HCl ?
The value of Kc for the reaction 3O2(g)⇌2O3(g) is 2.0×10−50 at 25oC. If the equilibrium concentration of O2 in air at 25oC is 1.6×10−2 M, what is the concentration of O3?
