SEM 2: CHAPTER 1: REACTION KINETIC (PART 1)

 1.1 : REACTION RATE

TABLE 1: SUMMARY OF REACTION RATE OF ZERO, FIRST & SECOND ORDER

There are 4 ways to determine order of reaction:

1. Refer to the unit of RATE CONSTANT, k

- each order has different unit of k.

- For example: 

   👉 ZERO ORDER - k = M/time or mol/L time or mol/dm3 time

   👉 FIRST ORDER - k = time-1 

   👉 SECOND ORDER - k = M-1 time-1 or L mol-1 time-1  or  dm3 mol-1 time-1

2. Initial Rate Method 

- comparing data based on given table of concentration with initial rate

3. Half life Method

4. Linear Graph Method

- To plot Linear graph, we refer to integrated rate law
