The unstable arrangement of atoms that forms momentarily at the peak of the activation-energy barrier is known as the activated complex. Activated complex is termed as a intermediate that is highly unstable and formed during the conversion of reactant into product. That is a short lived intermediate.
<span>Suppose you plant a seed and observe that a tree of large mass grows from it. The tree achieves a final mass that changes very little for years afterward.<span>
</span>Answer: Of the options presented above the one that is true about the tree is answer choice B) Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing, and both continue now even though the tree reached a stable mass.
I hope it helps, Regards.</span>
Generally speaking mechanical energy is energy which physically moves (the object), while the thermal energy is energy from the movement of atoms.
Basically temperature is a measurement of atomic movement (doesn't move object as a whole).
Hence heat.
Answer:
The correct answer is option e.
Explanation:

Moles of phosphorus pent-oxide :

According to reaction, 1 mole of phosphorus pent-oxide is obtained from 5 moles of oxygen gas.
Then 0.05 mole of phosphorus pent-oxide will be obtained from:

Hence,the correct answer is option e.
Explanation:
If the concentration of a substance is changed, the equilibrium will shift to minimise the effect of that change. If the concentration of a reactant is increased the equilibrium will shift in the direction of the reaction that uses the reactants, so that the reactant concentration decreases. For example, decreased volume and therefore increased concentration of both reactants and products for the following reaction at equilibrium will shift the system toward more products.
