Explain what change would you expect on the rate of the sn2 reaction of 1-iodo-2-methylbutane with cyanide ion if the nucleophile concentration is halved and the alkyl halide concentration is halved?
Explain what change would you expect on the rate of the reaction of ethanol with 2-iodo-2-methylbutane if the nucleophile concentration is unchanged as well as the alkyl halide concentration is doubled?
Calculate the number of moles of carbon dioxide in the final equilibrium system obtained by initially adding 1.00 mol of H2, 2.00 mol of CO2, 0.750 mol of H2O, and 1.00 mol of CO to a 5.00 L reactor at 990ºC.
Calculate the standard enthalpy of the reaction, Delta(H) rxn}, for the thermite reaction: 2Al(s) + Fe2O3(s) ----> 2Fe(s) + Al2O3(s) Elements in their standard state have an enthalpy of formation value of zero

The compound below is treated with chlorine in the presence of light. Draw the structure for the (organic) species produced by reaction of the compound with a chlorine atom. Assume reaction occurs at the weakest C-H bond.
the equilibrium would shift to the right producing more products the equilibrium would shift to the left producing more reagents the equilbrium would not be effected by the created pressure change the equilibrium would speed up the equilibrium wou..
