Answer:
Explanation:
Hello there!
In this case, according to the given chemical reaction whereas the sodium chloride is in a 2:1 mole ratio with chlorine, the required moles of the later are computed as shown below:
So we cancel out the moles of NaCl to obtain:
Best regards!
Answer: E. It decreases the value of Eact.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Your answer is :
P = K * x where P is partial pressure K is Henry's constant and x is solubility
<span>775 torr = K L·torr/mol * 0.0.0347 mole / liter </span>
<span>K = 775 / 0.0347 = 22334 L·torr/mol </span>
<span>in the second solution we have </span>
<span>1670 = 22334 * x </span>
<span>x = 1670 / 22334 </span>
<span>= 0.075 moles CO2 per liter of water.
</span>
