Compounds A and B are unstable and each decomposes by a first-order process. At 398 K, the rate constant for the decomposition of A is 3.6 X 10-5 s-1. Separate containers of A and B were prepared, with initial concentrations of 0.120 M A and 0.240 M B. After 5 hrs, it was found that the concentration of A was...

An enzyme that follows Michaelis-Menten kinetics has a KM value of 20.0 μM and a kcat value of 211 s−1. At an initial enzyme concentration of 0.0100 μM, the initial reaction velocity was found to be 1.07×10−6 μM/s. What was the initial concentration of the substrate, [S], used in the reaction ? Express your answer in micromolar to three significant...

Problem 4 In a lab experiment, a cart of mass 2 kg, moving initially to the right at 3 m/s, collides head-on with a cart of unknown mass, moving initially to the left at 2 m/s. As a result of the collision, the carts bounce back with exactly the opposite velocity of what they had going in. Assume the system...

4. Draw a free energy reaction coordinate diagram for both a generic endergonic and a generic exergonic reaction (label each). Make sure to label the x- and y-axes. Now label where reactants and products should go on the figure. Draw something that illustrates the free energy change for each reaction. Now write something like the following next to your figures: “reactants...
