The reaction O3 + NO → O2 + NO2 has Ea = 10.7 kJ/mole and ΔH = – 199.8 kJ/mole. What is the activation energy for the following
inysia [295]

Answer:

Ea = 210.5kJ/mole

Explanation:

When the reaction:

O3 + NO → O2 + NO2

Occurs, requires 10.7kJ/mole and releases -199.8kJ/mole.

For the forward reaction:

O2 + NO2 → O3 + NO

The Ea is the sum of Ea of the forward reaction and - ΔH, that is:

Ea = Ea - (-ΔH)

Ea = 10.7kJ/mol - (-199.8kJ/mol)

Ea = 210.5kJ/mole

a remote control toy jet fighter has a mass of 5 kg and can travel up to 60 m/s. what is the kinetic energy of the toy jet fight
prohojiy [21]

Answer:

9000J

Explanation:

Given parameters:

Mass of the jet fighter  = 5kg

Velocity  = 60m/s

Unknown:

Kinetic energy of the jet fighter  = ?

Solution:

The kinetic energy of a body is the energy due to motion of the body.

It is mathematically expressed as;

    K.E  = \frac{1}{2} m v²

m is the mass

v is the velocity

 So;

     K.E  =  \frac{1}{2}  x 5 x 60²  = 9000J
