100
The speed of a chemical reaction
What is reaction rate?
100
The heat of reaction is...
What is "the energy difference between the reactants and products"?
100
What happens if a collision has correct orientation but insufficient energy?
no reaction!!!
100
What is reaction order if we double concentration but reaction rate remains same?
0 order
100
What is the air speed velocity of an unladen African swallow?
24 mph
200
the area of chemistry concerned with the speed at which reactions occur
What is Chemical Kinetics?
200
when the energy of the products is less than the energy of the reactants
What is endothermic reactions?
200
What is formed from a collision?
An activated complex.
200
SO2 + O3 ----> SO3 + O2 SO2 is 2 order O3 is 0 order What is the rate law for this reaction?
rate = k[SO2]2 . [O3]0
200
Pronounce κίνησις
Nice try!
300
the energy needed to start a reaction.
What is activation energy?
300
Which line (blue/green) is the endothermic reaction?
The green line
300
What collision theory states?
That in order for molecules to react, they must collide
300
it shows how the rate of a reaction depends on the concentration of the reactants
What is rate law?
300
the study of the chemical reactions that are catalysed by enzymes
What is Enzyme kinetics
400
When two molecules have an effective collision, a temporary, high energy (unstable) chemical species is formed
What is activated complex?
400
what does the rate of reactions depend on?
The presence of catalysts, surface area, Concentration, Temperature
400
2 things that must happen for the collision theory to happen
Collisions must have the correct orientation, Collisions must have sufficient energy to break bonds
400
Why were 10 points taken from Gryffindor?
For Hermione Granger’s Obsessive babyfat.
400
The theory of Chemical creation through collision states that atoms must have exact coordination and speed, what happens in the center of a quazar when that needed velocity is increased past the theoretical speed of light?
Now that you wasted five minutes reading the question, the answer is fusion and black hole creation.
500
they hold one reactant molecule in proper orientation for reaction to occur when the collision takes place
Define heterogeneous catalysts
500
what does the graph show?
an exothermic reaction with and without a catalyst.
500
How do we call this equation? k = A(e^-Ea/RT)
arrhenius equation
