S.R.P or oxidising power (Z>Y>W>X/ text Reactivity downarrow) [S.R.P uparrow= Reactivity downarrow]

Q. If the standard reduction potential $E^{\circ}$ for four divalent elements $X, Y, Z, W$ are $- 1.46 V, - 0.36 V, 0.15 V$ and $- 1.24 V$ respectively then

$X$ will replace $Z^{2 +}$ from aqueous solution

$Y$ will replace $Z^{2 +}$ from aqueous solution

Wwill replace $Z^{2 +}$ from aqueous solution

All statements are correct.

S.R.P or oxidising power $\frac{Z > Y > W > X}{Reactivity ↓}$ [S.R.P $↑=$ Reactivity $↓]$

Q. If the standard reduction potential E∘ for four divalent elements X,Y,Z,W are −1.46V,−0.36V,0.15V and −1.24V respectively then

X will replace Z2+ from aqueous solution

Y will replace Z2+ from aqueous solution

Wwill replace Z2+ from aqueous solution
