Consider the following single step reaction in gas phase at constant temperature. (2 ~A _ ( g ) + B _ ( g ) C _ ( g ) ) The initial rate of the reaction is recorded as ( r ₁ ) when the reaction starts with (1.5 ~atm ) pressure of ( A ) and (0.7 ~atm ) pressure of ( B ). After some time, the rate ( r ₂ ) is recorded when the pressure of ( C ) becomes (0.5 ~atm ). The ratio ( r ₁: r ₂ ) is ______ ( 10⁻¹ ). (Nearest int
