Question

consider the following reversible reaction equation

Consider the following reversible reaction equation: 2502(g) + O2(g) → 2503(9) Ka = 1.2 x 103 Complete the following sentences (a-e) by selecting the best choice from the dropdown menus. a) This is an example of a equilibrium. b) At equilibrium, this system will contain mostly c) If more SO2 is added to this system at equilibrium, the reaction will shift towards the d) If oxygen gas is removed from this system at equilibrium, the reaction will shift towards the e) If the volume of this system at equilibrium is increased the reaction will shift towards th heterogeneous homogeneous products reactants

Answer 1

a) homogeneous. Because all reactants and products are in the same phase.

b) products. Because the value of equilibrium constant is large (K = 1200).

c) products. To consume the added SO2 i.e. the reactant, net reaction will shift in the direction of products as per Le Chatelier's principle.

d) reactants. To refurnish the lost amount of oxygen, reaction will occur in the direction of reactants as per Le Chatelier's principle.

e) reactants. To occupy the increased volume, reaction will shift toward the direction having greater number of moles (the reactant side here) as per Le Chatelier's principle.

Answer 2

1. homogenous

2. product

3. product

4. reactant

5. ractant
