👉 The proceed fluid, also known as the prograde fluid or simply fluid, is a critical component in chemical reactions where it facilitates the movement of reactants and products between different phases, such as from a solid to a liquid or gas phase. This fluid enables the mixing and interaction of molecules, allowing reactions to occur more efficiently by overcoming energy barriers. It's particularly important in heterogeneous catalysis and biological systems where it aids in the transport of substances across phase boundaries, ultimately driving the reaction forward and ensuring effective conversion of reactants into products.
