14

## To work out k, the formula is

### k = rate/ [A][B]

15

## The slow step shows the reactant dependant on the reaction so if a reactant isnt there will it be in the rate equation?

### no

16

## Order of reaction can be worked out from the slow or fast step?

### SLOW

17

## Anthing burned is always: endo or exo

### Exothermic

18

## Why is combustion exothermic?

### Change of state increases disorder

19

## What is the only thing that can affect the equilibrium constant?

###
Temperature!!!

20

## Does increasing the concentration of products or reactants in the equilibrium constant do anything?

### NAW, only temperature

21

## In evaporation reactions, ∆H is

### positive

22

## In evaporation reactions, ∆S is

### Positive

23

## If ∆G is negative then equilibrium lies to the

### RHS

24

## ∆G is known as Gibb's free energy or

### standard free energy

25

### Positive

26

## For a reaction to be feasible ∆G must be?

### Negative

27

## If K>1, then ∆G is

### negative

28
