If the reaction CH4(g) + O2(g) <--> CO2(g) + 2H2O(g) is not yet in equilibrium, what is the effect of adding a catalyst?
Group of answer choices
product/reactant ratio will be the same as without catalyst, but equilibrium will be reached faster
more reactants will be present at equilibrium than if no catalyst were added
more products will be present at equilibrium than if no catalyst were added
no way to determine
Homework Answers
Catalyst provides a diffrent path to the reaction which require less activation energy. if activation energy is less, reaction be faster. So catalyst will make reaction faster and equilibrium will reach faster. But catalyst doesnt affect the equilirium constant or extent of reaction or relative amount of reactants and priducts.
A is the correct answer
