The rate law for the reaction, A---C+k is given as: Rate=K[A]The unit of K will be:

Correct answer: C. s-1

  • A. mole-1dm3s-1
  • B. mole1dm-3s-1
  • C. s-1
  • D. mole-1dm3

Explanation

Zero-order: k = same as rateFirst-order: k = "per unit time"Second-order and higher: k includes powers of volume and inverse concentration

About Chemical Equilibrium

Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
