The rate equation for the reaction $2\text{A}+\text{B}\to \text{C}$ is found to be: $\text{rate}=k[\text{A}][\text{B}]$. The correct statement in relation to this reaction is that the:

Consider the following $E^{\circ }$ values:$E_{{\text{Fe}}^{3+}/{\text{Fe}}^{2+}}^{\circ }=0.77\text{V}$$E_{{\text{Sn}}^{2+}/\text{Sn}}^{\circ }=-0.14\text{V}$ Under standard conditions the potential for the reaction:$\text{Sn}(s)+2{\text{Fe}}^{3+}(aq)\to 2{\text{Fe}}^{2+}(aq)+{\text{Sn}}^{2+}(aq)$ is:

The molar solubility product of a salt ${\text{A}}_2{\text{B}}_3$ is $K_{sp}$. The solubility '$s$ ' is given in terms of $K_{sp}$ by the relation:

The standard e.m.f. of a cell, involving one electron change is found to be $0.591\text{V}$ at $25^{\circ }\text{C}$. The equilibrium constant of the reaction is ($F=96,500{\text{C mol}}^{-1};R=8.314{\text{JK}}^{-1}{\text{mol}}^{-1}$):

The enthalpies of combustion of carbon and carbon monoxide are $-393.5$ and $-283{\text{kJ mol}}^{-1}$ respectively. The enthalpy of formation of carbon monoxide per mole is:
