Answer:
The collision theory is defined as the rate of a reaction is proportional to the rate of reactant collisions.
Explanation:
The reacting species should collide with orientation that allows contract between the atoms that will become bonds together in the product.
The collision occurs with adequate energy to permit mutual penetration of the reacting species. The two physical factors based on the orientation and energy of collision, the following reaction with carbon monoxide with oxygen is considered.
2CO(g) + O2(g) → 2CO2 (g)
After collision between the carbon monoxide and oxygen the reaction is
CO(g) + O2(g) → CO2 (g) + O(g)
Based on the theories of chemical reaction the molecules collide with sufficient amount of energy an activated complex is formed.
Your answer is B. 6.02 x 1023 grams
Here we assume that disintegration has occur so the normal t½ formular will not be used
mathematically we..⅛×5600 =700
therefore it is about 700years option A
First, we need to get moles of NaOH:
when moles NaOH = volume * molarity
= 0.02573L * 0.11 M
= 0.0028 moles
from the reaction equation:
H3PO4(aq) + 3NaOH → 3 H2O(l) + Na3PO4(aq)
we can see that when 1 mol H3PO4 reacts with→ 3 mol NaOH
∴ X mol H3PO4 reacts with → 0.0028 moles NaOH
∴ moles H3PO4 = 0.0028 mol / 3 = 9.4 x 10^-4 mol
now we can get the concentration of H3PO4:
∴[H3PO4] = moles H2PO4 / volume
= 9.4 x 10^-4 / 0.034 L
= 0.028 M
