3. Upon heating, the gas cyclopropane (CH2)a undergoes isomerization to form propene (CH2CH=CH2) The rate constant for this first-order reaction is 6.7 x 10^s? If the flask is initially 0.50 M in cyclopropane with no propene present, what will be the molarity of both cyclopropane and propene after 15 minutes? How many minutes will it take for the flask to be 0.1 M in cyclopropane and 0,4 M in propene? Also, calculate the half-life of this reaction. Hint: minutes must...
