Chemical equilibrium Flashcards
What is the unit for rate of reaction?
mol dm^-3s^-1
What does collision theory state?
-Particles must collide
-Particles must have sufficient energy
How do you work of rate of reaction at a certain point on a graph?
Draw a tangent
What is the name of the graph used in rate of reaction?
Boltzmann distribution curve
What effect does increase in temperature have on BDC?
-more collisions have energy above Ea.
-More successful collisions
Name the x, y axis in a BDC.
X- Energy
Y- no. of particles
What are the two types of Catalysts and what makes them different to one another?
Homogenous- Same phase of matter (s), (s)
Heterogenous- Different phase of matter (s), (g)
What effect does catalyst have on the BDC?
Ea Shifted to the left so more particles speed up chemical reaction
What is the name of the graph used to measure chemical reaction?
Boltzmann distribution curve
What variable is used to equilibrium constant?
Kc
What is the equation for Kc?
Products/Reactants
What happens if Kc is more than 1?
Equilibrium shifts to products side (right)
What happens if Kc is less than 1?
Equilibrium shifts to reactants side (left)
What happens if Kc is equal to 1?
No shift
Kc =
[Products]/[Reactants]
