Given reaction is `2X_((gas)) + Y_((gas))hArr2Z_((gas)) + 80` Kcal
Which combination of pressure and temperature gives the highest yield of Z at equilibrium ?

Options

A. 1000 atm and `500^(@)C`
B. 500 atm and `500^(@)C`
C. 1000 atm and `100^(@)C`
D. 500 atm and `100^(@)C`

Answer

C

Explanation

The reaction takes place with a reduction in number of moles (volume) and is exothermic. So high pressure and low temperature will favour the reaction in forward direction.
