Definition
The change of the concentration/ the change in time
average reaction rate
the starting point of a reaction
reactants
cutting down reactants into smaller pieces
increasing surface area
the rate law is = product of the specific rate constant and _________
concentration of reactant/s
R = K [A]m[B]n
What do we call m+n ?
Reaction order
when the catalyst and the reactants exist in a different physical state
heterogeneous reaction
the final point a reaction reaches on an energy diagram
products
Which factor is adjusted when we add more reactants to the reaction mixture
concentration
Which unit the concentration of reactants in the rate law is measured in?
Molarity M
X + Y = XY
If the reaction order in X is 2 and the reaction order in Y = 1 ,, what is the overall reaction order?
3
unstable compound formed when reactants change to products
activated complex
the top of the energy diagram
activated complex
Which factor is adjusted to increase number of collisions between particles
temperature
What is the only thing that affects the specific rate constant of any rate law?
Temperature
C + D = W
If this reaction has the following rate law
Rate = K[D]
What does that mean for c ?
the reaction order in C = Zero
the minimum amount of energy required to start the reaction
activation energy
the distance between reactants and activated complex
activation energy Ea
a factor that decrease the amount of activation energy required for reactions to occur
catalyst
There is no question !!!!!!
Bonus
A + B = C
a reaction has an overall order 5
If the reaction order for the B = 1 what is the reaction order for A?
4
a substance used as food preservation
An inhibitor
When the reactants have higher energy than products
energy is released / exothermic reaction
What makes lithium to react faster than sodium in water
nature of reactants ( Li is above Na in the activity series)
True or False
The value of K is different from one reaction to another
True
A reaction has the following rate law
Rate = K[C] [D]2
What will happen to the rate when the concentration of D is doubled?
the rate law will become fourfold ( 4*rate)
