Chemistry Basics
the study of the rates of reaction and the pathways taken
chemical kinetics
What happens to the reaction rate if the temperature increases
reaction rate increases
A short lived, high energy unstable arrangement of atoms is called
activation or transition state
what helps speed up a reaction without being used up in the reaction
catalyst
What is Barbies full name
Barbara Millicent Roberts
H2 + I2 --> 2HI
Name the reactant
H2 + I2
Which will rust faster a metal bar, metal strips or metal shavings
metal shavings
Where on a potential energy diagram is the transition state located
the top of the curve
The overall rate of chemical change depends of which step
the slowest
Who holds the world record for the fastest man alive
Usain Bolt
H2 + I2 --> 2HI
What do we call the 2HI in the equation
product
what is the minimum energy required to cause a collision
activation energy
What are molecules doing during the activation or transition state
breaking apart and forming new bonds
liquid SO2 and H2O are combined with a liquid catalyst which type of catalyst is used
homogeneous
Which animal is 30 times more likely to be hit by lightning than people
giraffe
two things that must be true for a chemical reaction to happen
correct speed and orientation
If the concentration of particles decrease, what happens to the reaction rate
reaction rate decrease
When the products are greater in energy than the reaction (uphill)
endothermic
what is a biological catalyst called
enzyme
How much is Taylor Swift worth
$1.1 billion
What theory states the greater the frequency, the greater the energy of collision, the greater the reaction rate?
Collision Theory
