Increase the temperature (explained in the Collisions Theory) causes the particles to move faster (and so collide more frequently) and also have a higher energy so the collision is more likely to end in a reaction (as two particles must have a minimum energy in order to react).
Increasing the surface area increases the number of particles that can collide and so increases the rate of reaction.
The same is true with increasing pressure/ concentration.
Adding a catalyst lowers the energy required for a reaction to occur so increases the rate of reaction.

Increasing the pressure will increase the reaction rate because it will force the particles to be closer together, and so the likelihood of particles colliding increases. Increasing the temperature can also increase the rate of a reaction because the particles will be more energised and more likely to move around and collide.

The kinetic molecular theory states that all particles of an ideal gas are
Marizza181 [45]

THE KINETIC MOLECULAR THEORY STATES THAT ALL PARTICLES OF AN IDEAL GAS ARE IN CONSTANT MOTION AND EXHIBITS PERFECT ELASTIC COLLISIONS.

Explanation:

An ideal gas is an imaginary gas whose behavior perfectly fits all the assumptions of the kinetic-molecular theory. In reality, gases are not ideal, but are very close to being so under most everyday conditions.

The kinetic-molecular theory as it applies to gases has five basic assumptions.

  • Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size.
  • Gas particles are in constant rapid motion in random directions.
  • Collisions between gas particles and between particles and the container walls are elastic collisions.
  • The average kinetic energy of gas particles is dependent upon the temperature of the gas.
  • There are no forces of attraction or repulsion between gas particles.

A sample of neon gas occupies a volume of 752ml at 25k. What volume will the gas occupy at 80k if the pressure remains constant
Anettt [7]

Answer:

The gas occupy 2406.4 mL at 80 K.

Explanation:

Given data:

Initial volume of gas = 752 mL

Initial temperature = 25 K

Final temperature = 80 K

Final volume = ?

Solution:

The given problem is solved by using charle's law.

V₁/T₁ = V₂/T₂

V₂ =  V₁. T₂ /T₁

V₂ = 752 mL × 80 k / 25 K

V₂ = 60160 mL. k/25 K

V₂ =  2406.4 mL
