Activation energy is the energy needed to begin breaking the bonds of reactants and is denoted as option D.
<h3>What is a Reactant?</h3>
These are the substances which take part in a chemical reaction and result in the formation of the product.
The activation energy is required as it breaks the bonds of the reactant thereby resulting in the product being formed. This therefore makes it the most appropriate choice.

Everything is made of atoms. An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
Its been awhile since I've dabbled in chemistry, but i do know that A isnt the answer because the question says solution, not mixture. This looks somewhat like a trick question, it says individual components, so the answer would be C. This is because the individual components do react to form a compound. B and D would be true if it didnt say individual components, so the question is basically focusing on only one ingredient, not the whole solution. Answer: C
We have the value of
Total energy produced in the chemical reaction=653 550 KJ
Time needed=142.3min
To calculate the rate of energy transfer, that is the amount of energy produced per minute.
Rate of energy transfer=
=
=4592.76 KJ min⁻¹
So, the rate of energy transfer is 4592.76 KJ min⁻¹.
write the equation for the reaction
that is 6 F2 +P4 =4 PF3
find the theoretical mass that is
let the theoretical yield be represented by y
theoretical yield = 78.1/100 = 120/y
y= 153.6 grams
find the number of moles of PF3
moles = mass/molar mass
= 153.6/87.97 =1.746 moles
by use of mole ratio between F2 :PF3 which is 6:4 the moles of F2 is therefore= 1.746 x 6/4 = 2.62 moles
mass = moles x molar mass
= 1.746 moles x38 g/mol = 99.6 grams
