Problem

For a given chemical reaction γ1A+γ2B→γ3C+γ4D\gamma_1 A + \gamma_2 B \rightarrow \gamma_3 C + \gamma_4 D Concentration of C changes from 10 mmol dm−310 \text{ mmol dm}^{-3} to 20 mmol dm−320 \text{ mmol dm}^{-3} 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 mmol dm−3 s−19 \text{ mmol dm}^{-3} \text{ s}^{-1} . Therefore the rate of reaction is ______ mmol dm−3 s−1\text{mmol dm}^{-3} \text{ s}^{-1} . (Nearest Integer) [JEE MAINS - ONLINE - 2022]
