The decomposition of A into B is represented by the exothermic reaction, A ⇌ 2B. To achieve maximum decomposition, it is desirable to carry out the reaction ?
Correct answer: C. At low P and low T
- A. At high P and high T
- B. At low P and high T
- C. At low P and low T
- D. At high P and low T
Explanation
The forward reaction is exothermic, so low temperature shifts equilibrium toward B. Because the products contain two moles instead of one, low pressure also favours decomposition of A.
