B. Influence of Temperature on Reaction Rates Most chemical reactions speed up when the temperature is increased. Chemists sometimes use the rough rule of thumb that a 10 C increase in temperature will double the rate of a reaction. The influence of temperature on a reaction rate will be studied using the same reactions that were used in Part A. Reaction temperatures wil be established and maintained by water baths. Procedure 1. For each trial listed in Table 11.3, measure the KIO, solution and dis- tilled water into a clean, dry 10-cm test tube as you did in Part A Measure the NaHSOs solution into a clean, dry 15-cm test tube as you did in Part A 2. Before mixing the reactants, bring them both close to the same tem- perature by placing them in a water bath made from a 250-mL beaker containing about 150-mL of water. The water is adjusted to the ap propriate temperature. Leave them in the bath for at least 5 minutes before mixing

For the gas-phase reaction 2H2+O22H2O rxnG is 457.18kJ. What does a graph of G versus lnQ lnQ varying from 50 to +50 look like at 25C? Change the temperature and find out if the graph looks substantially different at different temperatures.
In the PhET Reactions tab to observe how multiple atoms and molecules interact under varying conditions. Select a molecule to pump into the chamber. Set the initial temperature and select the current amounts of each reactant. Select Show bonds under Options. How is the rate of the reaction affected by concentration and temperature?
use the kineticmolecular theory to explain why an increase in temperature increases reaction rate.
Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?
For the following two reactions H+Cl2HCl+Cl H+Br2HBr+Br the first reaction has a lower value of A than the second reaction. What can one say about the relative properties of the intermediates HCl2 and HBr2, just from the relative values of A?
Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A and B are mixed, and after 12.0minutes the measured concentration of C is 0.396mol/L. b. Pure A,B, and C are mixed together at equal concentrations of 0.300M. After 8.00minutes, the concentration of C is found to be 0.455M.
