will work with up to 3 partners (similar to a lab group) to prepare a written report which analyzes kinetic data that has been provided to you. All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...
Need help with the first picture. Data provided in pictures #2 & #3 Determining the Activation Energy and Collision Frequency Factor for Reaction 1 Part 1.

Calculate the natural logarithm of the rate constant. In ) and...
Do case #4 Background: The data shown on the following page was obtained from Tension Tests of 10 unknown ductile metals. For each test, various dimensions and loads were measured before and after failure. The data is a summary of readings taken during the test (loads vs extensometer readings). Purpose: To determine the stress, strain, yield stress and modulus of elasticity of a circular shaped specimen from a tension test. Directions: A. For your particular case (depending on your last...
