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

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
