The first-order rate constant for the reaction of methyl chloride (CH3Cl) with water to produce methanol (CH3OH) and hydrochloric acid (HCl) is 3.32 10-10s-1 at 25 degrees C. Calculate the rate constant at 34 degreesC if the activation energy is 116 kJ/mol.
Ethers react with HI to form two cleavage products. One of the products might react further with HI. In the first box below draw the two major products that could be recovered after treatment with one equivalent of HI
Calculate the VOLUME (mL) of liquid H2O formed if the reaction goes to completion and you condense the water vapor.
