For the gas phase reaction, `C_(2)H_(4)+H_(2)hArrC_(2)H_(6)(Deltah=-32.7kcal)` carried out in a vessel, the equlibrium concentration of `C_(2)H_(4)` can be increased byA. Increasing the temperatureB. Decreasing the pressureC. Removing some `H_(2)`D. Adding some `C_(2)H_(6)`

Answer» Correct Answer - A::B::C::D
(abcd) The reaction is exothermic, hence increasing temperature will favour backward reaction (i.e., conc. Of `C_(2)H_(4)` increases). Again decreasing pressure, removing `H_(2)` and adding `C_(2)H_(6)` favours backward reaction.
