<u>Answer:</u> The activation energy of the reverse reaction is 47 kJ/mol
<u>Explanation:</u>
The chemical equation for the decomposition of dinitrogen pentaoxide follows:
We are given:
Activation energy of the above reaction (forward reaction) = 102 kJ/mol
Enthalpy of the reaction = +55 kJ/mol
As, the enthalpy of the reaction is positive, the reaction is said to be endothermic in nature.
To calculate the activation energy for the reverse reaction, we use the equation:
where,
= Activation energy of the forward reaction = 102 kJ/mol
= Activation energy of the backward reaction = ?
= Enthalpy of the reaction = +55 kJ/mol
Putting values in above equation, we get:
Hence, the activation energy of the reverse reaction is 47 kJ/mol
I think it’s radiation, that’s what i got from looking it up
Answer:
Density
Explanation:
If the fishing weight is more dense than the water, it will sink and if it less dense it will float. hope this helps :)
Answer:
1. Students need to measure masses of the items.
2. Put baking soda and vinegar in a plastic bag and close it.
3. Mix the two, allowing for a reaction to occur.
4. Figure the mass of the plastic bag while the two components are inside.
5. The combined mass should be equal to what each weighed on their own.
