Please answer this question. Thank you!

(Chapter 2) 1. Solid-state reactions are the most widely used methods for inorganic compounds, however, they usually have slow kinetics and long reaction time due to the relatively slow nucleation and diffusion rates at the solid-solid interfaces. For many solid-state reactions, there are several reaction parameters that can be optimized to achieve a reasonable reaction rate. a. Name three strategies that can improve the reaction rate under a fixed temperature and pressure. Explain your choices. b. What are the factors one must consider in order to optimize the reaction temperature? Show your reasoning. (hint: considering reaction rate, produc purity, sintering effect, operation and separation cost, etc)
