What are factors affecting chemical equilibrium?

Answer 1

The equilibrium position is determined mostly by the concentration of products and the concentration of reactants. If the reaction is either exothermic or endothermic (and most are one or the other) than adding or removing heat will affect the equilibrium position. And if there are gases involved in the reaction, in particular if there are more moles of gas on one side of the reaction than the other, than the pressure will affect the equilibrium position.

Answer 2

R=K[a]A[b]B[c]C/[d]D

R=rate

K=Rate constant

a,b,c=concentration of reactants (this could be a list several items long)

d=concentration of products

A,B,C,D = order of reactants power quotients.

Answer 3

1) Effect of change of concentration

By increasing or decreasing the concentration of one of the reactants or products, the reaction can be manipulated in the desired direction.

To increase the yield of NH3 the concentration of N2 or preferably H2 should be increased in the synthesis of ammonia.

2) Effect of change of pressure

* Reactions which proceed with decrease in volume are favored by high pressures.

* On the other hand, reactions which proceed with increase in volume are favored by low pressures.

* If the volume remains the same then change in pressure has no effect.

3) Effect of change in temperature

Exothermic reactions will be favored by decrease in temperature

Endothermic reactions will be favored by increase in temperature.

4) Effect of catalyst

The presence of a catalyst in a reversible reaction does not affect the state of equilibrium but only causes the reaction system to attain equilibrium in a shorter period of time.

Answer 4

the main factors that control the rate of the reaction are:

1. The nature of the reactants.

2. The surface are exposed.

3. The concentrations

4. The temperature

5. Presence of a catalyst.

6. Presence of an inhibitor.

Answer 5

The object of the net force is acting as a zero. Sum of forces in x and y direction are zero. Because of inertia, the object at equilibrium does not change its motion either at rest or constantly moving in motion.

It tells you how far a reaction will go, before the concentrations of the products get so high that the reverse reaction equals the forward reaction.

Answer 6

the following are factors that affect equilibrum reaction:

change in concentration can

change in temperature change in pressure

catalyst

Answer 7

The number of successful collisions :)
