Equilibrium and kinetics

Question 1

What do we need to have a reaction take place

Answer 1

1. Enough force in the collision 2. the right orientation

Question 2

Ectothermic

Answer 2

If the products have less energy than the reactants

Question 3

Endothermic

Answer 3

If the products have more energy than the reactants

Question 4

Equilibrium

Answer 4

when the rate of the foreword reaction equals the rate of the reverse reaction

Question 5

If k>1,

Answer 5

It favors the products

Question 6

If k

Answer 6

it favors the reactants

Question 7

Le chateliers principle

Answer 7

It is possible to shift an equilibrium to favor the reactants or the products

Question 8

How does heat affect equilibrium

Answer 8

If heat is added, the equilibrium will shift to the side with the heat. If we remove it, it will shift away

Question 9

How does adding substances affect equilibrium

Answer 9

If you add a substance, the equilibrium will shift away from it, if you remove it, than twoards

Question 10

How does pressure affect equilibrium

Answer 10

only for gasses) increasing the pressure shifts the equalibrium to the side with fewer moles of gas.

In heat+H2S+I2 = 2Hi + S Adding more s

Answer 11

Shifts left

Question 12

In heat+H2S+I2 = 2Hi + S Cooling the system

Answer 12

Shifts left

Question 13

In heat+H2S+I2 = 2Hi + S Increasing the pressure

Answer 13

Shifts left

Question 14

In heat+H2S+I2 = 2Hi + S Removing h2s

Answer 14

Shifts left

Question 15

In heat+H2S+I2 = 2Hi + S Increasing the volume

Answer 15

Shifts right

Question 16

What does a catalyst do

Answer 16

It lowers the activation energy

Question 17

Ways to speed up a reaction

Answer 17

1. Heat it up 2. Particle size. (Increase the surface area) 3. Add a catalyst (speeds up a reaction by lowering the activation energy - not used up in the reaction 4. Increase the concentration 5. Shrink the volume (primarily with gasses)
