Catalyst onlya)Decreases activation energyb)increases activation energyc)Brings about equilibriumd)None of theseCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Negative catalyst increases activation energy

Answer

Catalyst don't change activation energy of a reaction.... it's proceeds the reaction in an alternate manner in which the requirement of activation energy is low.... So, it would be the answer 'None of these' or 'Brings about equilibrium' because catalyst helps to achieve equilibrium fast. We can't conclude whether it decreases the activation energy or not

Answer

Catalysts are both negative and positive of which negative increases activation energy while positive decreases activation energy

Answer

The substance which alter the rate of chemical reaction generally increase the rate of chemical reaction without involving in that chemical reaction but only by its presence.............. catalyst decreases the activation energy of chemical reaction so that rate of chemical reaction get increases .......

Answer

Catalyst provide an alternate path by decreasing threshold Energy barrier and hence decreasing activation energy...

Answer

Yes, the correct option is A

You may know that solvent means water,Likewise generally catalyst means positive catalyst.

So,the positive catalyst increase the rate of the reaction by decreasing the activation energy.

Answer

Negative catalyst decreases activation of energy

Answer

The Effect of Catalysts on the Activation Energy Barrier. Catalysts provide a new reaction pathway in which a lower A.E. is offered. A catalyst increases the rate of a reaction by lowering the activation energy so that more reactant molecules collide with enough energy to surmount the smaller energy barrier.

Answer

Catalyst provides an alternative  pathway for the reaction in which low activation energy is offered. Thus more reactant molecules collides with minimum energy forming products. Thus it increases rate of reaction by decreasing activation energy .
