The change of pressure can be observed on the reactions which involves gaseous substances. According to Le-Chateliers’s principle, increase of pressure on a system at equilibrium will shift the equilibrium…
The reaction will be given as: PCl5 ⇌ PCl3 Cl2 Initial moles: PCl5 = 0.10 PCl3 = 0 Cl2 = 0 Equivalent moles: PCl5 = 0.10 – α PCl3 =…
Effect of addition of inert gas like helium, neon etc has the following effects on the equilibrium constant: There are two cases on which equilibrium depends. These are: (1) Addition…
The Equilibrium constant expression involves the concentrations or partial pressures of the reactants and products. The units of Equilibrium constant K will depend on the number of moles of reactants…
Relation between Kp and Kc is given as: Kp = Kc (RT) ∆n Kc = Kp / (RT) ∆n T = 700 K R = 8.314 J mol -1 K-1…
PCl5 dissociates as: PCl5 ⇌ PCl3 Cl2 If α is the degree of dissociation at certain temperature under atmospheric pressure, then Initial concentration: PCl5 = 1 PCl3 = 0 Cl2…
For the homogeneous gaseous reaction 2 AB2 (g) ⇌ 2 AB (g) + B2 (g) Derive an expression for the degree of dissociation, α, in terms of Kp and total…
Difference between rate of reaction and reaction rate constant are as follows: RATE OF REACTION REACTION RATE CONSTANT Rate of reaction is the change in concentration of a reactant or…
In case of chemical reactions i.e. reactions involving a number of atoms, ions, molecules of the reactants in the balanced equation, the chances for all the atoms, ions or molecules…
A series of step reactions or elementary processes proposed to account for the overall reaction is called the mechanism of the reaction. The writing of step reactions is usually based…
