no. the amount of catalyst does not influence the reaction; A catalyst simply provides an alternative route for the reaction with a lower activation energy.
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.
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
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. :)
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.
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.

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.
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.
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!
