JEE Main 2022 Chemistry question

ChemistryChemical KineticsJEE Main 2022

For a given chemical reaction , concentration of C changes from 10 m mol to 20 m mol in 10 seconds. Rate of appearance of D is 1.5 times the rate of disappearance of B which is twice the rate of disappearance of A. The rate of appearance of D has been experimentally determined to be 9 m mol . Therefore, the rate of reaction is m mol . (Nearest Integer)

Answer: 1

Solution

d[C]/dt = (20 − 10)/10 = 1 m mol . Let = −d[A]/dt. Then −d[B]/dt = and d[D]/dt = . Since d[D]/dt = 9, . The stoichiometric coefficients follow from the rate
