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

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
