By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
decrease in reactants and increase in products
Catalysts do not affect the equilibrium, they only speed up the reaction.
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
None. A catalyst can speed up a chemical reaction that would occur anyway, but it will not change the point of equilibrium.
The law of mass action stipulate that the rate of a chemical reaction is directly proportional to the product of the activities (or concentrations) of the reactants.
As long as angular amplitude is kept small, the period does not depend on the angular amplitude of the oscillation. It is simply dependent on the weight. It should be noted that to some extent period actually does depend on the angular amplitude and if it gets too large, the effect will become noticeable.
The position of an object has no effect on the location of its center of gravity. It may have an effect on the truck's center of gravity, however, if the truck's load shifts on the incline. But that's the result of an actual shift in the center of gravity, not the result of the incline.
Initial displacement has no effect on the period of oscillation. The period T = 2(pi)sqrt(mass/spring constant)
* forward rate = reverse rate* constant environmental conditions (e.g.: T, P, etc.; otherwise, Le Chatelier's Principle comes into effect)* closed system
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)
No.
The mass action effect is the shift in the position of equilibrium through the addition or removal of a participant in the equilibrium.

A catalyst speeds up the rate of a reaction.
equilibrium conversion is that which is at equilibrium concentration
The temperature of a reaction will entirely change th equilibrium position for any given reaction. If I'm right, as you increase the temperature, the equilibrium shifts closer to the endothermic reaction as there is more heat to consume. It may also, of course, change other properties of the substances involved in the reaction, but that depends on the chemicals.
A catalyst alters the rate of a chemical reaction.
A catalyst speeds up the rate of a reaction.
The law of mass action stipulate that the rate of a chemical reaction is directly proportional to the product of the activities (or concentrations) of the reactants.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
