Uniform concentration can be achieved through various methods: - Effective Mixing: Proper agitation or mixing of the reaction mixture ensures that reactants are evenly distributed. - Optimized Reactor Design: Utilizing reactor designs like Continuous Stirred Tank Reactors (CSTR) or Packed Bed Reactors can help in maintaining uniform concentration. - Controlled Addition of Reactants: Gradually adding reactants in a controlled manner can prevent concentration gradients.
