Flashcards in 18.1 - Orders, rate equations, and rate constants Deck (10):

1

## What is the equation for rate of reaction?

### Change in concentration / change in time

2

## What are the units of rate?

### mol dm-3 s-1

3

## What are common orders of reaction?

###
Zero order

First order

Second order

4

## How would you show the order of a reactant?

###
[A]0

[A]1

[A]2

5

## How will zero order with respect to the reactant affect the rate?

### It doesn't affect the rate of reaction

6

## How does first order affect the rate?

### If concentration of A is doubled, rate increases by a factor of 2 to the power of 1

7

## How does a second order reaction affect the rate?

### If the concentration of A is doubled, the rate quadruples

8

## State the rate equation

### Rate = k [A]m [B]n

9

## What is k?

### Rate constant
