Think critically a golf ball and a bowling ball are mov-
ing and both have the same kinetic energy. which one is
moving faster? if they move at the same speed, which
one has more kinetic energy?

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
