In the reaction a and b is to C and equilibrium is established them the pressure the is equal in the other equilibrium which day is exchange change day if this
Answers
Answer:
A+B⇌C+D. If initially the concentraion of A and B are both equal but at equilibrium, concentration of D will be twice of that of A, then the equilibrium constant of the reaction will be 4.
A+B⇌C+D
Initial concentration (M) t=0 a a 0 0

At equilibrium, concentration of D will be twice of that of A.
