In the reaction `A_(2)(g) + 4B_(2)(g)hArr2AB_(4)(g)`, `Delta H lt 0` . The decomposition of `AB_(4)` (g) will be favoured atA. Low temperature and high pressureB. High temperature and low pressureC. Low temperature and low pressureD. High temperature and high pressure |
Answer» Correct Answer - B `2AB_(4)(g)hArrA_(2)(g) + 4B_(2)(g)` , `Delta H = +ve` As decomposition of `AB_(4)` is endothermic, so reaction proceeds with increase in temperature. Secondly forward reaction proceeds with increase in number of moles of products, so low pressure favours it. |
