H 2 O (ℓ) leftharpoons H ( aq )++ OH - ( aq ) For ionization of H 2 O: Δ H >0 ⇒ ENDOTHERMIC On temperature increase reaction shifts forward ⇒ both [ H +]and [ OH -]increase ⇒ p H p O H decreases

Q. For the following Assertion and Reason, the correct option is :
Assertion : For hydrogenation reactions, the catalytic activity increases from Group 5 to Group 11 metals with maximum activity shown by Group 7 -9 elements.
Reacion : The reactants are most strongly adsorbed on group 7 - 9 elements.

The assertion is true, but the reason is false

Both assertion and reason are true but the reason is not the correct explanation for the assertion

Both assertion and reason are true and the reason is the correct explanation for the assertion

Both assertion and reason are false

$H_{2} O (ℓ) ⇌ H_{(a q)}^{++} O H -_{(a q)}$
For ionization of $H_{2} O : Δ H > 0 \Rightarrow EN D OT H ERM I C$
On temperature increase reaction shifts forward
$\Rightarrow$ both $[H^{+}]$ and $[O H^{-}]$ increase
$\Rightarrow p H & pO H$ decreases

The assertion is true, but the reason is false

Both assertion and reason are true but the reason is not the correct explanation for the assertion

Both assertion and reason are true and the reason is the correct explanation for the assertion

Both assertion and reason are false

H2​O(ℓ)⇌H(aq)++​OH−(aq)​ For ionization of H2​O:ΔH>0⇒ENDOTHERMIC On temperature increase reaction shifts forward ⇒ both [H+]and [OH−]increase ⇒pH&pOH decreases
