The equilibrium constant for the reaction of hydrogen gas and oxygen gas to produce water at 500 k is 2.4 × 1047. what does the magnitude of the equilibrium constant tell us about the reaction? 2 h2(g) + o2(g) ⇄ 2 h2o(g) k = 2.4 × 1047

Given reaction:

2H2(g) + O2(g) ↔ 2H2O (g)

The equilibrium constant can be expressed as

1) a ratio of the concentration of products to that of the reactants

Keq = [H2O]²/[H2]²[O2] = 2.4 * 10⁴⁷

2) It can also be expressed as a ratio of the rate of forward reaction to that of the reverse

Keq = k(forward)/k(reverse)

Since the Keq value is quite high, this implies that k(f) >> k(r). i.e. the rate of formation of product (water) is much higher than the reactant

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
