41. Physical states ( of reactants or products ) matter, as do molar concentrations. 42. Several reactions are required to obtain the gaseous reactants required for Fischer Tropsch catalysis. 43. Usually, the more complex the reactant molecules, the lower the steric factor. 44. Furthermore, for multiple reactants , conversion can be defined overall or per reactant. 45. Furthermore, for multiple reactants, conversion can be defined overall or per reactant . 46. Usually, the more complex the reactant molecules, the lower the steric factors. 47. Contrary to common perception, PTC is not limited to systems with hydrophobic reactants . 48. An excess of one reactant can be used to control the degree of polymerization. 49. So we represent the active enzyme as a powerful reactant of the enzymatic reaction. 50. Both the reactants and the products have bonds.
