What will happen if more heat is applied to the following system at equilibrium?

X\(_2\)(g) + 3Y\(_2\)(g) ⇌ 2XY\(_3\)(g); ∆H = xKJmol\(^{-1}\)

  • A the yield of XY 3 will decompose
  • B more of XY3 will decompose
  • C More of X2 will react
  • D the forward reaction will remain static

The correct answer is C. More of X2 will react

Increase in temperature will cause the forward reaction to occur, increasing the amounts of the products and decreasing the amounts of reactants.
