What are the features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
What does a catalyst not do?
Catalysts do not change the postition of the reaction's equilibrium. Adding a catalyst will increase the rate of reaction, but it will do this by providing another pathway for the reaction to occur acros, meaning a lower activation enthalpy is needed. :)
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
What are the salient features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.

Can a catalyst change the rate constant for a reaction?
A catalyst can change the rate constant for a reaction by providing an alternative reaction pathway with lower activation energy. This lowers the energy barrier for the reaction, allowing more reactant molecules to successfully undergo the reaction, thus increasing the rate constant for the reaction.
Would a catalyst cause an endothermic reaction to become exothermic?
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Does a catalyst make a reaction exothermic?
I honestly think it would because a catalyst lowers the activation energy, the amount of energy needed to complete the reaction. Since the activation energy is lower, it is absorbing less energy. I guess if its becoming less endothermic, its becoming more exothermic. Hope this helped!
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
What causes a reaction but does not disappear or change?
A catalyst
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
