| $P(10 \ mL $ of $0.1 M NaOH +20 \ mL$ of $0.1 M $ acetic acid$)$ diluted to $60 \ mL$ | $1$ the value of $\left[ H ^{+}\right]$ does not change on dilution |
| $Q (20 \ mL $ of $ 0.1 \ M \ NaOH +20 \ mL $ of $0.1 \ M $ acetic acid$)$ diluted to $ 80\ mL$ | $2$ the value of $\left[ H ^{+}\right]$ changes to half of its initial value on dilution the value of $\left[ H ^{+}\right]$ changes to two times of its initial value on dilution |
| $R(20 \ mL $ of $ 0.1 \ M HCl +20 \ mL$ of $0.1 \ M$ ammonia solution$)$ diluted to $80 \ mL$ | $3$ the value of $\left[ H ^{+}\right]$changes to $1 / \sqrt{2}$ times of its initial value on dilution |
| $S10 \ mL$ saturated solution of Ni $( OH )_2$ in equilibrium with excess solid Ni $( OH )_2$ s diluted to $20 \ mL ($solid Ni $( OH )_2$ is still present afterdilution$).$ |
$4$the value of $\left[ H ^{+}\right]$changes to $\sqrt{2}$ times of its initial value on dilution |
| $5$ the value of $\left[ H ^{+}\right]$changes to $\sqrt{2}$ times of its initial value on dilution |
${H_2}C = C{H_2}(g) + {H_2}(g) \to {H_3}C - C{H_3}(g)$ at $298 \,K$ will be ....$kJ$
$F{e^{ + 3}}\left( {aq} \right) + {e^ - } \to F{e^{2 + }}\left( {aq} \right);{E^o} = + 0.77\,V$
$A{l^{ + 3}}\left( {aq} \right) + 3{e^ - } \to Al\left( s \right);{E^o} = - 1.66\,V$
$B{r_2}\left( {aq} \right) + 2{e^ - } \to 2B{r^ - };{E^o} = + 1.09\,V$
Considering the electrode potentials, which of the following represents the correct order of reducing power?
