Answer:
K = [HI]² / [H₂] [I₂]
Explanation:
To write the expression of equilibrium constant, K, it is important that we know how to obtain the equilibrium constant.
The equilibrium constant, K for a given reaction is simply defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant is written as follow:
K = [Product] / [Reactant]
Now, we shall determine the equilibrium constant for the reaction given in the question above. This can be obtained as illustrated below:
H₂(g) + I₂(g) —> 2HI (g)
K = [HI]² / [H₂] [I₂]
The relation between force, mass of an object and its acceleration is given by following equation
F = mass of object X acceleration
The unit of Force is Newton (N)
unit of acceleration is ms⁻²
unit of mass if Kg
[all these are SI units]
Mass of object =
mass of sprinter =
The chemical with the lowest point is helium
