The kinetics of decomposition of dinitrogen pentaoxide is studied at 50 degrees c and at 75 degrees c. which of the following statements concerning the studies is correct?
a. the rate at 75 will be greater thatn the rate at 50 because the activation energy will be lower at 75.
b> the rate at 75 will be greater thant the rate at 50 because the activation energy will be higher at 75.
c. the rate at 75 will be less than the rate at 50 because the molecules at higher speeds do not interact as well as those at lower speeds.
d. the rate at 75 will be greater than at 50 because the concentration of a gas increases with increasing temp.
e. the rate at 75 will be greater than the rate at 50 because the number of molecules with enought energy to react increases with increasing temp.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
