(c) What is H for the reaction? (d) What is the activation energy of the reverse reaction? (e) At what point would C2H6 certainly be found? (f) What is any species at point C called?

7-12 Two kinds of gas molecules are reacted at a set temperature. The gases are blown into the reaction vessel from two tubes. In setup A, the two tubes are aligned parallel to each other; in setup B, they are 900 to each other; and in setup C, they are aligned directly opposite each other. Which setup would yield the most effective collisions?

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?

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 statements: In general, the rate of a chemical reaction increases a bit at first because it takes a while for the reaction to get warmed up. After that, however, the rate of the reaction decreases because its rate is dependent on the concentrations of the reactants, and these are decreasing. Indicate everything that is correct in these statements, and indicate everything that is incorrect. Correct the incorrect statements and explain.

Jeneen v Try Again Your answer Is wrong. In additlon to checking your math, check that you used the right data and DID NOT round any Intermedlate calculations. The reform reaction between steam and gaseous methane (CH,) produces "synthesis gas," a mixture of carbon monoxide gas and dihydrogen gas. Synthesis gas is one of the most widely used Industrial chemicals, and is the major industrial source of hydrogen. dlo Suppose a chemical engineer studying a new catalyst for the reform reaction finds that 419. liters per second of methane are consumed when the reaction is run at 263. °C and the methane is supplied at 0.93 atm. Calculate the rate at which dihydrogen is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. kg x10 X…
