100

This kind of reaction has multiple steps

What is a stepwise reaction?

100

A reaction in which no mass is added, but mass is taken away

What is an elimination reaction?

100

This kind of atom is neutral overall, but very reactive

What is a radical?

100

BDE is an abbreviation of this

What is bond dissociation energy?

100

The energy required for a reaction to proceed

What is activation energy?

200

This graph shows a reaction having this kind of mechanism

what is concerted?

200

A reaction that is a net neutral in terms of mass loss or gain

What is a substitution reaction?


200

This kind of bond breaking results in radicals

what is homolytic?

200

BDE is the energy required to break a bond in this way

What is homolytically?

200

This letter represents the transition state

What is letter C?

300

This graph shows a reaction with energy

What is Endothermic?

300

This reaction type typically breaks double bonds

What is an addition reaction 

300
This kind of reaction produces heat or energy

What is Exothermic?

300

This kind of reaction requires energy input

What is endothermic?

300

This is how a catalyst decreases the activation energy of a reaction

What is by stabilizing the transition state?

400

This is the rate-limiting step in this reaction

What is step 2


400

This kind of reaction involves proton transfers.

What is an acid-base reaction?

400

These kinds of products are favored over the reactants

What are lower energy products?

400

BDE is used to calculate this

What is Delta H or Enthalpy?

400

This is the value of Keq when delta G is 0

What is 1?

500

This graph shows a reaction with a Keq of this size


What is a Keq>1?

500

Dehydration reactions fall under this category

What is elimination reactions?

500

This is an unstable positively charged carbon
