Question

rate constant for forward step=_________Rate constant for backward step A. Kc B. Lower C. high D. catalyst​

Answer 1

answer : option (A) K_c

explanation : it is based on kinetic theory of chemical reactions.

at equilibrium constant,

rate of forward reaction = rate of backward reaction.

and equilibrium constant = rate constant of forward/rate constant of backward

⇒K_c = rate constant for forward step/rate constant for backward step

⇒rate constant for forward step = K_c × rate constant for backward step

hence, option (A) is correct choice.
