Options
- A1 . 9 × 10 - 63
- B2 . 4 × 10 31
- C1 . 2 × 10 21
- D4 . 38 × 10 - 32
Correct answer
D. 4 . 38 × 10 - 32
Step-by-step solution
K c = 3 .0 × 10 - 59 O 2 g = 4 × 10 - 2 . The given reaction 3 O 2 g ⇌ 2 O 3 g K c = p r o d u c t   o f   m o l a r   c o n c e n t r a t i on   o f   p r o d u c ts p r o d u c t   o f   m o l a r   c o n c e n t r a t i o n   o f   r e a c t a n ts = O 3 g 2 O 2 g 3 Put all the given values in the expression of Kc 3 .0 × 10 - 59 = O 3 g 2 4 × 10 - 2 3 ⇒ [ O 3 ( g ) ] 2 = 3 .0 × 10 - 59 × ( 4 × 10 - 2 ) 3 ⇒ O 3
