( Delta T_{f}=i k f r ) [ begin{array}{c} 3 cdot 72=i cdot 1 cdot 86 cdot 1 i=2 end{array} ] ( 100+1 ) isnization memp dogree of dissociation is 2 [ begin{array}{l} alpha^{prime}=1 alpha=frac{i-1}{n-1} 1=frac{2-1}{n-1} end{array} ] ( [infty=2] cdot .07 .8 ) the number of iong given by coosplex on dissociation in ( mathrm{H}_{2} mathrm{O} ). So, the Cossplen is [ left[p+c l_{3}left(H_{2} Oright)_{3}right] c l cdot 3 h_{2} omega rightarrowleft[P t c_{3}(M, 0)_{3}right] ] Hence the the correct representrition of 5 complex iss [ left[P t c l_{3}left(H_{2} Oright)_{3}right] C l cdot 3 h_{2} 0 ] OPHon (B) is correct
