Molecularity of a reaction

A CSTR is to be designed in which an exothermic liquid phase first order reaction of the type, A → R, is taking place. The reactor is to be provided with a jacket in which coolant is flowing. Following data is given: C_A0= 5 kmole/m³; X_A = 0.5; Feed temperature = reactor temperature = 40°C. Rate constant at 40°C = 1 min^-1; (ΔH) = -40 kJ/mole; ρ = 1000 kg/m³ C_P = 4 J/gm.°C; q = 10^-3 m³/min (ρ and C_P are same for the reactant and product streams). The amount of heat to be removed is
