Chemical equilibrium

Question 1

What is the unit for rate of reaction?

Answer 1

mol dm^-3s^-1

Question 2

What does collision theory state?

Answer 2

-Particles must collide
-Particles must have sufficient energy

Question 3

How do you work of rate of reaction at a certain point on a graph?

Answer 3

Draw a tangent

Question 4

What is the name of the graph used in rate of reaction?

Answer 4

Boltzmann distribution curve

Question 5

What effect does increase in temperature have on BDC?

Answer 5

-more collisions have energy above Ea.
-More successful collisions

Question 6

Name the x, y axis in a BDC.

Answer 6

X- Energy
Y- no. of particles

Question 7

What are the two types of Catalysts and what makes them different to one another?

Answer 7

Homogenous- Same phase of matter (s), (s)
Heterogenous- Different phase of matter (s), (g)

Question 8

What effect does catalyst have on the BDC?

Answer 8

Ea Shifted to the left so more particles speed up chemical reaction
