How can equilibrium of a closed system chemical reaction be disturbed? Select all that apply.
charle [14.2K]

The correct answers are :

Changing the volume of the system.

Changing the temperature of the system.

Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.

As the system is closed, we cannot add or remove products or reactants.

Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.

Also change in volume  will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.

Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.

Explanation:

The correct option of all is that transverse waves have motion perpendicular to velocity while longitudinal waves have motion parallel to velocity.

A wave is a disturbance that transmits energy from one point to another. There several types of waves like sound, electromagnetic , ocean waves etc.

  • Waves can be classified as either longitudinal or transverse waves based on the direction through which they are propagated.
  • Longitudinal waves are waves propagated parallel to the source of velocity.
  • An example is sound waves and seismic p-waves.
  • They have series of rarefaction and compression along their path.
  • Transverse waves are propagated perpendicular to their source.
  • An example is electromagnetic waves in which electrical and magnetic fields vibrates perpendicularly.
