Study the reaction. NH4+ + NO2– ⟶ N2 + 2H2O

The rate of this reaction is proportional to the concentration of ammonium (NH4+) and the concentration of nitrogen dioxide (NO2–).

What is the rate law of this reaction?

Rate = K[N2][H2O]2
Rate = K[NH4+]2
Rate = K[NH4+][NO2–]
Rate = K[NO2–]2

Rate = K[NH4+][NO2–]

Explanation:

Hello there!

In this case, since rate laws include the concentration of the species contributing to the rate of a chemical reaction; this question asserts this reaction is proportional to the concentration of ammonium (NH4+) and the concentration of nitrogen dioxide (NO2–); therefore, the rate law must contain the concentration of both reactants, for that reason, the answer would be Rate = K[NH4+][NO2–] as it contains the concentration of the aforementioned species.

Regards!

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
