Explanation / Answer

rate of a reaction = change in concentration/changein time

rate -1= (1.200*10^12-1.144*10^12)/(1.87-0.00) = 2.99*10^10molecules /cm^3.s

rtae-2 =(1.144*10^12-1.106*10^12)/(3.74-1.87)= 2.032*10^10 molecules/cm^3.s

rate-3 = (1.106*10^12-1.080*10^12)/(5.61-3.74) = 1.39*10^10 molecules/cm^3.s

rate-4= (1.080*10^12-1.064*10^12)/(7.48-5.61) = 8.556*10^9 molecules /cm^3.s
