What is an endothermic reaction? What is delta h?

Energy is ABSORBED by the reaction, positive

What side of the equation is the endothermic number written on?

The reactants side

What is an exothermic reaction? What is delta h?

Energy is GIVEN OFF by the reaction, negative

In an exothermic reaction, what side of the equation is the number on?

The products side

What reaction is this an example of

Exothermic

What type of reaction is this an example of

Endothermic

This is an exothermic reaction, what would X be labeled as?

Reaction progress

This is an exothermic reaction, what would X be labeled as?

Delta H, aka the number on the products side

This is an exothermic reaction, what would X be labeled as?

Ea

This is an exothermic reaction, what would a an and b be labeled as?

a= reactants b=products

What type of energy diagram is this portraying

Endothermic

On an exothermic energy diagram, the reactants are _____ the products

Above

On an endothermic energy diagram, the reactants are _____ the products

Below

On an energy diagram, which is listed first?

Reactants

Where do you draw the ea on a energy diagram?

From the reactant line to the top of the arch

Where do you label delta h on an energy diagram?

The reactants line to the products line

If a catalyst is added to a reaction on an energy diagram, how would that change the diagram?

The arch would be smaller

Speeds up a chem reaction by lowering the activation energy (ea)

Catalyst/enzyme

Delta H Doesn’t affect the rate of the chemical reaction, but generally exothermic reactions are ___ than endothermic reactions

Faster

Define what rate of reaction means

How fast (increased rate) or slow (decreased rate) a reaction goes

What factors affect the rate of reaction

The concentration of each reactant, temperature, or if a catalyst is added

How does concentration affect the rate of reaction

The higher the concentration, the faster the reaction

How does temp affect rate of reaction

Higher the temp, faster the reaction

How does a catalyst affect the rate of reaction

Increases the rate
