In the following reaction, 2 S O 2 ( g ) + O 2 ( g ) → 2 S O 3 ( g ) The rate of formation of S O 3 is 100 g m i n - 1 . Hence, the rate of disappearance of C O 2 is
Options
- A50 g m i n - 1
- B20 g m i n - 1
- C100 g m i n - 1
- D200 g m i n - 1
Correct answer
B. 20 g m i n - 1
Step-by-step solution
In the reaction 2 SO 2 g + O 2 g 1 mol 32 g → 2 SO 3 g 2 mol 160 g Hence, 160 g of S O 3 is formed by 32 g of O 2 So 100 g of S O 3 will be formed = 32 160 × 100 = 20 g of O 2 So rate of disappearance of O 2 = 20 g m i n - 1 .
