The basic liquid phase reaction (A→2B) takes place in the batch reactor. When the temperature is increased from 300K to 330K, how much time decreases when x=0. 8? The reaction rate follows the basic rate law, and the concentration of the initial reactant is 5 mol·dm⁻³. The rate constant at 300K is 0. 1 min⁻¹, and the activation energy (Ea) is 100 kJ·mol⁻¹.
