7. Energy, Rate and Equilibrium

Why does increasing concentration generally increase the rate of a reaction?

For the reaction C(s, diamond) → C(s, graphite), ∆G = -0.693 kcal/mol (-2.90 kJ/mol) at 25 °C.

a. According to this information, do diamonds spontaneously turn into graphite?

What is meant by the rate of a reaction?

How would each of the following change the rate of the reaction shown here?

2 SO₂(g) + O₂(g) → 2 SO₃(g)

a. adding some SO₂(g)

How would each of the following change the rate of the reaction shown here?

2 NO(g) + 2 H₂(g) → N₂(g) + 2 H₂O(g)

c. removing some H₂(g)

How would each of the following change the rate of the reaction shown here? 2SO₂(g) + O₂(g) → 2SO₃(g)

a. adding more SO₂(g)
