For a reaction A → B

The rate of the reaction is

The equilibrium constant for the reaction, N₂ (g) + O₂ (g) ⇌ 2 NO (g) is 4 × 10^-4 at 2000 K. In presence of a catalyst, equilibrium is attained ten times faster. Therefore, the equilibrium constant, in presence of the catalyst, at 2000 K is

In which of the following cases does the reaction go farthest to completion

For a reaction, N₂ + 3H₂ ⇌ 2NH₃ , the value of K_c would depend upon

Which is not correct for an exothermic reaction

For the given reaction, 2A (s) + B (g) ⇌ C (g) + 2D (s) + E (s)  the degree of dissociation of B was found to be 20% at 300 K and 24% at 500 K. The rate of forward reaction

The gas A₂ in the left flask allowed to react with gas B₂ present in right flask as

A₂ (g) + B₂ (g) ⇌ 2AB (g) ; K_c = 4 at 27°C

What is the concentration of AB when equilibrium is established?

For the gas phase reaction, 2NO(g) ⇌ N₂ (g) + O₂ (g), ∆H = –43.5 kcal, which one of the following is true for N₂(g) + O₂(g) ⇌ 2NO(g)

The reactions, PCl₅ (g) ⇌ PCl₃ (g) + Cl₂ (g) and COCl₂ ⇌ CO (g) +  Cl₂ (g) are simultaneously in equilibrium in an equilibrium box at constant volume. A few moles of CO(g) are later introduced into the vessel. After some time, the new equilibrium concentration of

For the decomposition of PCl₅ g in a closed vessel, the degree of dissociation is 'x' at a total pressure 'P'.
