Question

Assertion :The reaction $Xe{O}_3+6H^{+}+6e^{-}\rightleftharpoons Xe+3H_{2}O,E^{\circ }=2.1V$ is not feasible thermodynamically to oxidise $H_{2}O$ Reason: There is a high activation energy barrier between oxidation state +6 and 0 of Xe.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true

Answer 1

The correct option is C Assertion is true but Reason is false

As $\Delta G^0=-nF{E}^0$ so thermodynamically it should oxidise but activation energy barrier between oxidation state +6 to 0 is very high so reaction doesnt takes place.
