Which phrase correctly describes temperature? a. average rotational kinetic energy of the particles in an object b. average energy of the particles in an object c. average translational kinetic energy of the particles in an object d. all energy possessed by the particles in an object

At a given temperature, a system of particles can be considered as point masses (m) each moving at a certain translational velocity (v). The motion of these particles can be defined in terms of their average translational kinetic energy which is responsible for the heat transfer during molecular collisions and therefore the temperature of the system.

The kinetic temperature T is given in terms of the average translational kinetic energy as:

T  = 2/3k(Kinetic energy)

T = 2/3k(1/2*m*v²)

where K = Boltzmann constant

Ans: C) Average translational kinetic energy

C. Average translational kinetic energy of the particles in an object

Explanation:

Kinetic energy is the energy of motion and any moving object has kinetic energy because it’s moving.  Translational kinetic energy is a type of kinetic energy that is produced when an object has from moving from one location to another.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
