Conclusion
‘s research
There are several potential conclusions for Barbara’s research on catalysts. One conclusion could be that catalysts can be used to improve the efficiency of chemical reactions. Another conclusion could be that catalysts can be used to reduce the amount of energy required for a chemical reaction to occur.
Additionally, catalysts can also be used to improve the selectivity of chemical reactions, meaning that they can help to ensure that only the desired products are produced.
