MARKING INSTRUCTIONS
The exercise carries 55 marks. The candidates shall be given one exercise out of exercises prescribed in the syllabus. The exercises in physical chemistry can be modified by the examiner and the same will be explained to the candidates. However, such modifications will not involve any departure from the basic principles over which experiments are prescribed in the syllabus.
Candidates shall be given one exercise out of the exercises prescribed in the syllabus.
The distribution of marks will be as follows
No marks for calculation will be awarded to a candidate for not calculating the result.
The permissible error will depend on the nature of the experiment. Generally, + 10% error may be taken as permissible error for experiments involving potentiometric and conductometric measurements. The constancy in values of rate constants may be taken into consideration while awarding marks in experiments on chemical kinetics. One mark shall be deducted for each + 2% error over permissible limit.
Oral questions shall generally be asked about the work assigned to the candidate. The purpose is to find out to what extent the candidate has an understanding of the basic principles of chemistry.
