Soybean oil is a mixture of different triglycerides of fatty acids (mostly unsaturated C18 and C16 acids) which can undergo epoxidation reaction to produce epoxidized products for use as additives in plastic industry. The epoxidation reaction can be generally expressed as: C57H98O6+mH2O2C57H98O12+rH2O (1) Determine the values of the stoichiometry coefficients ( m and r ) for the above reaction.
