Question
SO2Cl2 decomposes in the gas phase bythe reaction SO2Cl2(g)-->SO2(g) + Cl2(g) The reaction is first order in SO2Cl2and the rate constant is 3.0 x 10-6 s-1at 600 K. A vessel is charged with 2.4 atm ofSO2Cl2 at 600 K. The partial pressure ofSO2Cl2 at 3.0 x 105s is________atm? A. 0.98 B. 1.4 x 105 C. 2.2 D..76 E..29 SO2Cl2 decomposes in the gas phase bythe reaction SO2Cl2(g)-->SO2(g) + Cl2(g) The reaction is first order in SO2Cl2and the rate constant is 3.0 x 10-6 s-1at 600 K.

Formula : kt = ln P0 / P Where k is the first rate constant t is the time P0 is the initial partial pressure P is the partial pressure after t time Data : k = 3.0 x 10-6 s-1 t = 3.0 x 105s P0= 2.4 atm Upon substituting in theabove formula , 3.0 x10-6 s-1 * 3.0 x105s = ln ( 2.4 atm / x ) 0.9 =ln ( 2.4 /x ) 2.4 /x = 2.45 x = 2.45 /2.4 = 0.98 atmRelated Questions
