Consider the following equilibrium:

4fe(s) + 3 o2(g) < -- --> 2fe2o3(s);

which of the following equations is wrong?
kp=kc(rt)-5
kc=[o2]-3
kp= kc(rt)-3
kp = po2-3

The equation which is wrong is

Explanation:

For the given reaction:

The expression for is given by:

The concentration of solids are taken to be 1, only concentration of gases and liquid states are taken. The pressure of only gases are taken.

Relationship between is given by the expression:

where,

= number of moles of gaseous products - number of moles of gaseous reactants

R = gas constant

T= temperature

For the above reaction,

= number of moles of gaseous products - number of moles of gaseous reactants = 0 - 3 = -3

Hence, the expression for is:

Therefore, the equation which is wrong is

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
