RATE OF REACTION

rate of reaction is the speed at which reactants are converted into the products in a chemical reaction. There are few factors that affect the rate of reaction : surface area of a solid reactant, temperature, concentration, presence of catalyst and pressure(for gaseous reaction)

TIPS FOR SPM CHEMISTRY STUDENTS ( ANSWERING STRUCTURED AND ESSAYS QUESTIONS )

1. Read each question carefully before answering it.

2. Time yourself so you do not run of time.

3. Provide short answer to the question which start with the following words :
**List
**Name

7. Try to write something for every part of each question.

8. Set your answer neatly and logically. Untidy work make examiner difficult to read.

9. Use left over time to check all the questions. Ensure that :
**all chemical equation is balanced
**all chemica formulae is correct
**you give the full name of reagent

TIPS FOR SPM CHEMISTRY STUDENTS ( ANSWERING MULTIPLE-CHOICE QUESTIONS )

1. read each question carefully

2. read through all the alternatives before making decision

3. if you cannot answer a question, leave it out and return to it at the end

4. if you do not know the correct answer, you can improve your chances by eliminating as many wrong answer as possible

5. ensure you give an answer to every question
6. as a rough guide, spend not more than 1.5 minutes to each question
