A compound in a sample is degradable at high temperature, how will you inject that sample into gc column?

Based on your ICE table (Part 2) and the definition of Ka, set up the expression for Ka in order to determine the unknown. Each reaction participant must be represented by one tile. Do not combine terms.

2. 0.0042 moles of reactant in 50.0 mL is consumed in 278 sec, what is the rate of depletion? 3. What is the color of the solution at the STOP time? Account for the appearance of this color. Suppose your partner forgets to add the starch, how would this change your results? 4. In this redox reaction is being oxidized and is the oxidizing agent.

3. Draw a reaction energy diagram, and label the product (P), reactant (R), transition states (TS1, TS2, etc.), intermediates (INT1, INT2, etc.) and activation energies (AG‡₁, AG 2, etc.) for a reaction with the following criteria: i. A three-step, endothermic reaction; ii. AG3 > 0 but AG₁ AG‡₁ >> AG‡₂. Which species does the structure of the transition state of the rate-determining step resemble?
