Which of the following is one of the 12 principles of Green Chemistry?

Step-by-step solution

The 12 principles of Green Chemistry include the use of catalysts to enhance reaction efficiency (Catalysis). Catalytic reagents are superior to stoichiometric reagents as they can carry out a single reaction many times, reducing waste and energy consumption. The other options contradict the principles of Green Chemistry, which advocate for the prevention of waste, use of renewable resources, and use of safer (non-hazardous) solvents. Answer: Use of catalysts to enhance reaction efficiency
