1.	Which temperature and pressure will be to obtain more products in the following reaction ? Explain by Le-Chatelier principle. (i)N_(2(g)) + 3H_(2(g)) hArr 2NH_(3(g)) , DeltaH =-93.8 "kJ mol"^(-1) (ii)H_(2(g)) + CO_(2(g)) hArr CO_((g)) +H_2O_((g)) , DeltaH=+41 "kJ mol"^(-1) (iii)N_(2(g)) + O_(2(g)) hArr 2NO_((g)) , DeltaH=175 kJ (iv)CO_((g))+ 2H_(2(g)) hArr CH_3OH_((g)), DeltaH=-92.0 "kJ mol"^(-1)
Answer» Solution :(i) High pressure and low temperature gives more PRODUCTS. (ii) And (iii) there is no effect of pressure, but high temperature give more products. (IV) High pressure and low temperature gives more products.
