A 0.1M solution of styrene dissolved in toluene is stable for a much longer period than a sample of pure styrene. What is the reason for this. Pick the right answer
a) styrene polymerizes faster than toluene
b) the rate constant for polymerization of styrene is larger in toluene
c) the concentration of styrene is lower in the toluene solution than in pure styrene so all bimolecular polymerization steps occur more slowly.
d) the order of the reaction increases in toluene
e) styrene has a higher molecular weight than does toluene
