The most efficient way to determine whether a reaction is an exothermic chemical
reaction is to use —
A) an oxygen probe
B) a temperature probe
C) a pressure probe
D) a pH probe
...............................................................................................................
Answer:
Reaction is said to be exothermic in nature, if heat is evolved from the system. The resultant product formed is more stable. Since, during exothermic reaction, heat is given out be the system, temperature of system will increase. Hence, temperature is the probe to determine exothermic reaction.
Thus, correct answer is option B) a temperature probe

Explanation:
Answer:
15°
Explanation:
At the lowest temperature the gas will have the lowest rate of diffusion because diffusion deals with the motion of particles.
- Diffusion is the movement of particles from a region of high concentration to that of a lower concentration.
- According to the kinetic molecular theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules.
- The higher the temperature faster the molecules diffuse.
The gas with the lowest temperature will be the slowest to diffuse.
