Consider the following chemical equilibrium:
C(s) + 2H2 (g) <> CH4 (g)
Now write an equation below that shows how to calculate Kp from Kc for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator.

Kp = [CH₄(g)]/[H₂(g)]²(RT)⁻¹

Explanation:

C(s) + 2H₂(g) => CH₄(g)

Kp = Kc(RT)ⁿ

n= change in molar volumes of gas = 1 - 2 = -1

R = 0.08206 L·Atm/mol·K (gas constant)

T = Kelvin Temperature (arbitrary in problem) K =°C + 273

Kc = [CH₄(g)]/[H₂(g)]²  (measured values need to be in moles/L)

Kp = [CH₄(g)]/[H₂(g)]²(RT)⁻¹

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
