1.	If x is the fraction of PC l_(5) dissociated at equilibrium in the reaction, PC l_(5) hArr PCl_(3)+Cl_(2) then starting with 0.5 mole of PC l_(5), the total number of moles of reactants and product at equilibrium is___
Answer» `0.5-x` `x+0.5` `2x+0.5` `x+1` SOLUTION : TOTAL no, of MOLES at EQUILIBRIUM`=0.5-x+x+x=0.5+x`
