2SO2(g) + O2(g) \( \iff \)2SO3(g)

\( \bigtriangleup H = -395.7kJmol^{-1} \)

In the reaction above, the concentration of 2SO3(g) can be in creased by

  • decreasing the pressure
  • decreasing the temperature checkmark
  • the addition of catalyst
  • increasing the temperature

The correct answer is: B
