The yield of the products in the reaction,
`A_(2(g))+2B_((g))hArr C_((g))+Q` kJ would be higher at :

Options

A. high temperature and high pressure
B. high temperature and low pressure
C. low temperature and high pressure
D. low temperature and low pressure

Answer

C

Explanation

`underset(ubrace("1 mole 2moles")_("3moles"))(A_(2(g)) + 2B_(2(g))) hArr underset("1mole")(C_((g)) + QkJ`
According to Le Chatelier's principle, the equilibrium will shift in that direction in which pressure decreases i.e., decrease in the no. of moles. Thus, higher the pressure and lower temperature (in forward direction), better would be the yield of the product 'C'.
