What is the coordination number of chromium in \(\mathrm{K}_{3}\left[\mathrm{Cr}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)_{3}\right]\) ?

Consider the following reaction-

\(\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}_{2} \stackrel{\mathrm{Br}_{2} / \mathrm{NaCl}}{\longrightarrow}\)

Product of the reaction will be:

The basic principle of a hydrogen economy is:

The standard Gibbs free energy change and enthalpy change at \(25^{\circ} C\) for the liquid phase reaction

\(CH _{3} COOH ( l )+ C _{2} H _{5} OH ( l ) \rightarrow CH _{3} COOC _{2} H _{5}( l )+ H _{2} O\) (l) are given as \(AG ^{0}\) ags \(=-4650 J / mol\) and \(\Delta H ^{0}{ }_{298}=-3640J / mol\)

J/mol. If the solution is ideal and enthalpy change is assumed to be constant, then the equilibrium constant at \(95^{\circ} C\) is:
