7. nh2co2nh4(s) when heated to 450 k undergoes the following reaction to produce a system which reaches equilibrium: nh2co2nh4(s) ⇀↽ 2 nh3(g) + co2(g) the total pressure in the closed container under these condition is found to be 0.843 atm. calculate a value for the equilibrium constant, kp. a) 0.00701 b) 0.0888 c) 0.222 d) 0.599

Value of equilibrium constant is 0.0888

Explanation:

Both and are gaseous. Hence equilibrium constant depends upon partial pressures of and .

Initially no and were present.

Hence mole fraction of and at equilibrium can be calculated from coefficient of and in balanced equation.

Mole fraction of = (number of moles of )/(total number of moles of and ) =

Mole fraction of = (number of moles of )/(total number of moles of and ) =

Let's assume both and behaves ideally.

Therefore partial pressure of , and P_{CO_{2}}= x_{CO_{2}}.P_{total}

Where x represents mole fraction

So,

So,

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
