For the reaction represented below, the value of the equilibrium constant, Kp is 3.1 × 10-4 at 700 K. N2 (g) + 3H2 (g) ⇌ 2NH3 (g) Assume that the initial partial pressures of the gases are as follows: P(N2) = 0.411 atm, P(H2) = 0.903 atm, and P(NH3) = 0.224 atm. Which of the following is true? Q < K Q...

Calculate the equilibrium concentrations of N2O4 and NO2 at 25 ∘C if the initial concentrations are [N2O4]= 0.0130 M and [NO2]= 0.0300 M. The equilibrium constant Kc for the reaction N2O4(g)⇌2NO2(g) is 4.64×10−3 at 25 ∘C. I've worked through this problem a few times and still don't get the right answer. Can anyone show me the work??

A value commonly taken for the perception reaction time of motorists is delta t equals 1.5 seconds. Using this value determine the total stopping distance for a car traveling at 30 m/s. In calculating the stopping distance, lets assume that the vehicle continues at its initial speed for delta t, then decelerates to rest. A reasonable value for the deceleration...
