Determining the Rate Equation

Into a thoroughly washed and dried Erlenmeyer flask, place the required amount of H2C2O4 and any distilled water. The amounts are dictated by the experiment that you are doing. Reagents exp.1 exp. 2 exp.3 H2C2O4 20.00ml 20.00ml 10.00ml KMnO4 10.00ml 5.00ml 10.00ml H2O 0.00 ml

Gas Problem

Ammonia gas at 223 deg C and 90. atm flows into a reactor at a rate of 500. L/min. Carbon dioxide at 223 deg C and 47 atm flows into the reactor at a rate of 600. L/min. What mass of urea is produced per minute by this reaction assuming 100% yield?

Animal Testing and Estimation Calculations

1. Animal rights groups often target the LD50 standard as an example of callous indifference to animal welfare. Other groups argue that standards such as LD50 are necessary to ensure drug safety and effectiveness. Take a position on the issue and write a letter to the editor of a newspaper defending your position. 2. During a

Enzyme Kinetics

The enzyme succinoxidase adds oxygen to succinate to give fumarate. The reaction follows Michaelis-Menton kinetics. The following rate data were determined for a solution in which the enzyme concentration is 10.0 uM: [S](mM) ----------------- 0.33 10.00 vo (uM s-1) at 20 C ----- 0.50 1.17

Reaction Kinetics

In aqueous solution, the reaction of A to form B has the following rate expression: -d[A]/dt = k[A]{1 + k'[H+]} From the pH dependence of the reaction, k' was found to be 1.0 x 10e5 M-1. In a pH 4.0 buffer, it took 5 min for a 0.30 M solution of A to react to give 0.15 M solution B. Calculate the value of k and g
