Limiting reactants - Study guides, Class notes & Summaries

Enzyme Kinetics and Km - correct answer-The reaction catalysed by an enzyme uses exactly the same reactants and produces exactly the same products as the uncatalysed reaction. Like other catalysts, enzymes do not alter the position of equilibrium between substrates and products. Enzyme-catalysed reactions display saturation kinetics: For a given enzyme concentration and for relatively low substrate concentrations, the reaction rate increases linearly with substrate concentration; the enzym...

General Chemistry Semester 1 Exam Review | Latest Update | 2024/2025 | Graded A+ What is the difference between a heterogeneous and a homogeneous mixture, and how can each be separated? A heterogeneous mixture has visibly different components and can be separated by physical means such as filtration or decantation, while a homogeneous mixture has a uniform composition throughout and may require more complex methods like distillation for separation. How do you determine the empiric...
