If a reaction is at equilibrium and you add reactants what happens?

If you continuously add reactants even after the reaction has attained the equilibrium then according to Le Chatelier's principle, the reaction will again proceed in forward direction in order to neutralise the reactants and once again the attain the state of equilibrium.

What happens after you add just reactants to a reversible reaction?
In a reversible reaction, the reactants and products become to a dynamic equilibrium after some time. after gaining this equilibrium, when more reactants are added the equilibrium breaks. So according to the Le Chetelier principle, the reaction will proceed until the equilibrium is gained.
What will happen to the concentration of reactants after an equilibrium reaction shifts to the left?
Increasing the concentration of reactants will shift the equilibrium towards the products. The equilibrium will always shift to reduce the change you caused. If you add more products, it shifts toward reactants. This is known as the Le Chatelier Principle.See the Web Links to the left of this answer for more about this.
How is a reversible reaction shifted by addition of a substance?
Changing the quantities of the reactants or products in a reversible reaction causes the equilibrium to shift so that the equilibrium constant remains ... um ... constant.If the reaction isA + B = C + Dthen the equilibrium constant is [A][B] / [C][D]. If you add more A or B, then more A and B will be used up, and more C and D will be produced. If you add more C or D, then more C and D will be used up and more A and B will be produced.
What happens when you add pressure to an equilibrium?
Other aspects of the system (such as heat) will change to maintain equilibrium
What is mean of dynamic equilibirum in chemistry?
An equilibrium is a "balance", if something is in equilibrium then it is in balance. To add "static" is an unnecessary tautology except in the case of a mechanical equilibrium with zero linear momentum.

Why does forward reaction is decrease in rate as time increase?
This is because the reactants are being used up to make products. Unless you add more reactants to the solution, the rate at which products will be made will start to diminish until there is an equilibrium. At this point products will be converted to reactants and reactants will be converted to products and the equilibrium will not shift however the forward rxn and the reverse rxn will be occurring at the same rate

What does Le Châteliers principle state?
Le Chatelier's principle essentially states that if a stress is imposed on a system at equilibrium, the equilibrium will shift to minimize the stress. These stresses include: -Change in temperature -Change in pressure/volume (for gases) -Change in concentration A simple example of this: N2(g) + 3 H2(g) ⇌ 2 NH3(g) ΔH = −92kJ/mol -If you add N2(g) or 3 H2(g) the equilibrium will shift to the right (to the products), and more NH3(g) will be created so as to minimize the stress. - If you add NH3(g), the equilibrium will shift to the left (to the reactants), and more N2(g) and H2(g) will be created. -If you increase the temperature, the equilibrium will shift to the left (to the reactants). The reason for this is that the above reaction is exothermic, and releases heat. Consequently, the heat is on the side of the products, and thus if you add heat, the equilibrium will shift to the reactants and more N2(g) and H2(g) will be created. - If you increased the pressure, which is the same as decreasing the volume, the reaction will shift to the side with fewer moles, which, in this case, is the products. Thus, more NH3(g) will be created. -Conversely, if you decrease the pressure (increase the volume), the reaction will shift to the side with a greater number of moles, which, in this case, is the reactants. Thus, more N2(g) and H2(g) will be created. *It is important to note that changing pressure and volume only effects the equilibrium in gaseous reactions!

What simple experiment can you perform to test the hypothesis that an enzyme is not used up during the reaction?
Add more of the reactants under appropriate reaction conditions. If more product is made, this shows that the reactants are the limiting component and not the enzyme.
What is static equilibrium explain with example?
When reaction ceases to proceed, it is called static equilibrium. This happens mostly in physical phenomenon. For example , a building remains standing rather than falling down because all the forces act on it are balanced. This is an example of static equilibrium. --------------------------------------------------------------------------------------- An equilibrium is a "balance", if something is in equilibrium then it is in balance.
