Using the data in the table, determine the rate constant of the reaction and select the appropriate unit.

Determine the rate law for the reaction A + B - C+D given the following experiment data. Trial [A]o 1 0.25 0.75 0.50 0.75 4.

The half-life of a pesticide determines its persistence in the environment. A common pesticide degrades in a first-order process with a half-life of 6 days. What fraction (in decimal notation) of the pesticide remains in the environment after 20 days? Enter to 4 decimal places.

Write true if the statement is true, otherwise change the underlined word to make the statement true. 1. Metal A has a higher specific heat than metal B. If the two metals are independently applied with equal heat, it is expected that metal A will have a higher change in temperature. 2. The units for the rate constant of an over-all 1st order reaction is s', when the reaction time is measured in seconds. 3. If K is much greater than 1 (that is, K>>1), the equilibrium will favor the formation of reactants. 4. In the iron-thiocyanate system, increasing the pH would produce a dark orange solution. 5. For a weak acid HA, the equilibrium concentration of H3O* is equal to [HA]i. 6. The buffer region is the pH range where a buffer effectively neutralizes added acids and bases, while maintaining a relatively constant pH. A buffer can be expressed by the Henderson-Hasselbaich equation. 7. 8. Diluting a concentrated weak base, results to an increase in pH. 9. The plot of absorbance versus…
