10. The compound SO2012 decomposes in a first-order reaction SO2C12(g) → SO2(g) + C12(g) that has a half-life of 1.47 x 104 s at 600. K. If you begin with 1.6 × 10-3 mol of pure SO2C12 in a 2.0 L flask calculate at what time the amount of SO2C12 will be 1.2 x 10-4 mol. t1/2 In2/k→ 1.47 x 10.693/kk-4.71 x 10 initial concentration = (1.6 x 10)/2=8.0 x 10 final concentration = (1.2 x 10)/2= 6.0 x 10 In[A]=-kt+ In[A], In[6.0 x 10 ]=-(4.71 x 10)t + ln[8 x 10] -9.72 -4.71 x 10't-7.13 -2.59 -4.71 x 10't t-54989.38 sec or 5.50 x 10 sec - Kelly Hughes N
