3) mole bridge

4) back to grams

Question 4

is the H positive or negative in exothermic

Answer 4

Negative

Question 5

Is the H positive or negative in endothermic

Answer 5

Positive

Question 6

Fast Endo/ Exo has what changes

Answer 6

Smaller Ea

Question 7

Slow endo/exo has what changed

Answer 7

Larger EA

Question 8

Ways to change rate

Answer 8

1) temp

2) concentration

3) surface Area

4) pressure (only for gas)

Question 9

What change of rate only works for gas

Answer 9

Pressure

Question 10

Slowest to fastest states

Answer 10

1) Liquids/ Solids

2) Gas

3) Aqueous

Question 11

What factor does Aqueous have

Answer 11

1) 100% surface Area

2) 100% Mixed

3) Charged ion increase rate

Question 12

What does increasing temp do to rate graph

Answer 12

Gets shorter and wider

Question 13

What does decreasing temp do to rate graph

Answer 13

Gets longer and narrows

Question 14

What does increasing concentration do to rate graph

Answer 14

Gets higher up, gives more molec space

Question 15

What does decreasing concentration do to rate graph

Answer 15

Gets smaller and less space for molec

Question 16

What does adding a catalyst do to rate graph

Answer 16

The Ea gets smaller and shows up earlier on the graph

Question 17

How to know what is intermediate

Answer 17

Moves from products to reactants (disappears in step 1, comes back in step 2)

Question 18

How to know what is catalyst

Answer 18

Used in second step, comes back in third (doesn’t show up in overall )
