Question

Assertion :The splitting of water is associated with ps II. Reason: Water is split into$H^{+}$, $O_2$ and electrons.

• 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 correct but Reason is incorrect
• D. Assertion is incorrect and Reason are correct

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

The splitting of water is associated with the PS-II; water is split into H${}^{+}$, [O] and electrons. This creates oxygen, one of the net products of photosynthesis. The electrons needed to replace those removed from PS I are provided by PS II.

2H${}_2$O → 4H${}^{+}$ + O${}_2$ + 4e${}^{-}$

So, the correct option is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'
