The phenomenon of negative catalysis is also known as:

Correct answer: C. inhibition

  • A. auto catalysis
  • B. Self catalysis
  • C. inhibition
  • D. Enzyme catalysis

Explanation

Negative catalysis decreases the rate of a reaction and is therefore called inhibition. The likely distractor is autocatalysis, but autocatalysis occurs when a reaction product speeds up the reaction rather than slowing it.

About Factors Affecting Rate of Reaction

Reaction rate depends on the nature and concentration of reactants, pressure for gases, temperature, surface area and catalysts. Collision theory explains these effects through collision frequency, orientation and activation energy, while questions often distinguish a catalyst's effect on reaction rate from its lack of effect on equilibrium composition.
