Steam reforming methane (CH 4 ) produces synthesis a mixture of carbon monoxide and hydrogen gas, which the starting point for many important chemical syntheses. An chemist studying this reaction a tank 9.8 mol of methane gas and mol of water vapor and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 2.7 mol Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
