Question

The following reaction is a reversible reaction that exhibits high temperature behaviour:

• A. \( \text{MgO} + \text{Cl}_2 \rightarrow \text{MgCl}_2 + \text{O}_2 \)
• B. \( \text{O}_2 + 2\text{CO} \rightarrow 2\text{CO}_2 \)
• C. \( 2A + B \rightarrow 3C \)
• D. \( C + D \rightarrow 3E \)

Hint:

Reversible reactions may have their equilibrium shift with changes in temperature, and high temperatures often favour certain directions of the reaction.

Answer 1

The Correct Option is A

This reaction is reversible at high temperatures, where magnesium oxide reacts with chlorine gas to produce magnesium chloride and oxygen. The reaction is temperature dependent, and high temperatures favor the forward direction.

Step 2: Conclusion.
The reversible reaction that exhibits high-temperature behaviour is \( \text{MgO} + \text{Cl}_2 \rightarrow \text{MgCl}_2 + \text{O}_2 \), corresponding to option (a).
