In Homogeneous gaseous equilibrium, M(g) + 3N(g)--> 4P(g). Initial concentration of M is equal to that of N. If equilibrium concentrations of M and P are equal then what will be the value of KC?

A certain Zero order reaction has rate constant K is 0.025 MS^-1 for disappearance of A . What will be the concentration of A after 15 sec if initial concentration is A is 0.5M.

(A) 2.5 M  (B) 0.5 M (C) 1.5 M  (D) 0.125 M

The rate constant for zero order reaction is 2× 10^-2 Mole L^-1 sec-1. If the concentration of reactant after 25 sec is 0.5M ,the initial concentration must have been ?

(A) 1M (B) 2M (C) 1.5M  (D) 2.5M

Consider a general reaction A--->B follow zero order kinetics.if concentration of A is reduces from 0.1 M to 0.05 M in 10 second then calculate time taken when concentration reduce to 0.025 M.

(A) 2.5 sec  (B) 2 sec (C) 5 sec   (D) 10 sec

For the equilibrium, PCl 5​ (g)⇌PCl 3​ (g)+Cl 2​ (g) at 298K, K=1.8×10 −7 .Calculate ΔG 0 for the reaction (R=8.314JK −1 mol −1 ).
