Oh My God Chemistry Will be the End of Me

What Factors affect the rate of a chemical reaction?

• State of Reactants

• Concentration

• Temperature

• Presence of a Catalyst

• Surface Area

What is Rate Order?

• r=k[a]^m[b]ⁿ

• q=mc_p∆t

• ∆G=∆H-T∆S

What is Activation Energy?

• The minimum kinetic energy that particles must have for a chemical reaction to occur.

• The maximum kinetic energy that particles must have for a chemical reaction to occur.

What are transition states?

• Highest point of graph, an intermediate state between the initial and final states

• Beggining of graph,an ending state between the initial and final states

• End of graph, an beginning state between the final and initial states

What is an Intermediate?

• substance that is formed temporarily during a chemical reaction and is subsequently transformed into the final product

• substance that is formed permanently during a chemical reaction and is subsequently transformed into the final product

• substance that is formed permanently during a chemical reaction

What is a catalyst?

• A catalyst is a substance that speeds up a chemical reaction without interference.

• A catalyst is a substance that speeds up a chemical reaction with interference.

• A catalyst is a substance that slows down a chemical reaction without interference.

Endothermic or Exothermic?

• Endothermic

• Exothermic

Endothermic or Exothermic?

• Endothermic

• Exothermic

What is a rate-determining step?

• The slowest step

• The fastest step

What makes a reaction mechanism valid?

• The sum of elementary steps must add up to the overall chemical reaction.

• The way a reaction happens must match how fast we observe it happening.

• The way a reaction happens must not match how fast we observe it happening.

• The sum of elementary steps must not add up to the overall chemical reaction.
