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.
Answer:
0.30 mol/L
Explanation:
Mass = 108 g
Molar mass of glucose = 180.156 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given Volume = 2 L
<u>Molarity = 0.3 mol/L</u>
Answer:
The both refer to the same term.
Explanation:
The heat of neutralization also called the enthalpy of neutralization. It is the heat evolved or the enthalpy change when one equivalent of acid reacts with one equivalent of a base under standard conditions to form salt and water only.
