Answer:

False

Explanation:

For most reactions, raising the temperature leads to a faster reaction/higher rate of reaction. This is because a higher temperature means that the reactant particles have a higher average kinetic energy meaning more of them have enough activation energy needed to partake in a successful collision. Not only that because they have a higher average kinetic energy they are moving faster meaning more chances of collisions

How many moles of NaCl are present in 2.50 L of a 0.070 M solution?
posledela

Given :

Volume of NaCl solution 2.5 L .

Molarity of NaCl solution is 0.070 M .

To Find :

How many moles are present in the solution.

Solution :

Let, n be the number of moles.

We know, molarity is given by :

M = \dfrac{n}{V(in\ L)}

So,

n = M \times V\\\\n = 0.070\times 2.5 \\\\n = 0.175\ moles

Therefore, number of moles of NaCl is 0.175 moles.
