The following system is at equilibrium: \( 2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) \) with \( K = 4.3 \). What

What is the effect of doubling the pressure on the equilibrium? All other conditions remain unchanged. \( 2SO_2(g) + O_2(g)

What is required to convert a base into its conjugate acid?

Which changes increase the rate of the reaction? \( 2H_2O_2(aq) \rightarrow 2H_2O(l) + O_2(g) \) I. Introducing a catalyst II.
