In the given reaction,
`2X (g) + Y(g) hArr 2Z (g) + 80 ` kcal, Which combination of pressure and temperature will give the highest yield of Z at equilibrium?

Options

A. `1000 atm and 200 ^(@)C`
B. `500 atm and 500^(@)C`
C. `1000 atm and 100^(@)C`
D. `500 atm and 100^(@)C`

Answer

C

Explanation

In this equation, volume is decreasing and the reaction is exothermic, So, for the highest yield of Z, pressure should be high and temperature should be low.
