Factors affecting the position of equilibrium

 

Factors affecting the position of equilibrium

The position of equilibrium shifts to try to cancel out any changes you introduce.


Changing concentrations:

Increase the concentration of a reactant. This will make the forward reaction go faster for a while, until we reach equilibrium again. We have added more to the left-hand side, so the equilibrium shifts to the right, as if to remove it.

Changing temperature:

The position of equilibrium shifts to reduce the temperature.

Changing pressure:

Changing the pressure can also affect a mixture at equilibrium. However, there must be different numbers of gas molecules on either side of the equation. If you increase the pressure, the equilibrium shifts to try to reduce it again.



Q: Write any two factors affecting the position of equilibrium.

Ans: Concentration, temperature and pressure.

Answer Key for Grade-6 Social Studies 2nd final Term Examination 2021

Answer Key for Grade-6  Social Studies    2nd final Term Examination   2021 Page 85 Exercise 1:  What is the difference between climate and weather? Explain. The weather changes within a short time (24 hours or less), and it changes from day to day. While the climate is constant over a long period (it does not change from one day to another), and it characterizes the general atmosphere of a place over a long period. Exercise 2:  Name the four elements that affect the change of climate from one place to another or from one season to the other. 1. Temperature (heat) 2. Atmospheric pressure 3. Precipitation 4. Wind Exercise 3:  Write “true” or “false”. 1. Wind moves all the time above the surface of the Earth.  T 2. A barometer measures temperature.  F 3. Temperature refers to heat and the sun might be a possible source of heat.  T 4. When I say it’s going to be cloudy today, the I am referring to the weather.  T Page 100 Exercise...
