Question

For a given chemical reaction . Concentration of C changes from  to  in 10 s. 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 . Therefore the rate of reaction is . (Nearest Integer)

Canvas Classes · Accepted Answer

Rate of appearance of C:

Given:  (experimentally)

From stoichiometry relations given:
-  so 
-  so

Rate of reaction

From stoichiometry:

Rate of reaction . Since  (from the rate of change of C = 1 mmol/dm³/s and rate = 1):

Answer: 1 mmol dm⁻³ s⁻¹
