1. What is molarity of products? I can't decide if it's a. The concentration of the reactants measured in mol/L of solution or b. The concentration of the products measured in mol/L of solution
4. How does pressure relate to reaction rates? I'm stuck between a. Pressure is only important for gases or b. higher pressure in general reduces reaction rates. I think it might be B?
6. Reaction rate decreases as pressure increases. True?
1. The molarity of products refers to the concentration of the products of a chemical reaction, measured in mol/L (moles per liter) of solution.
To determine the molarity of products, you need to know the balanced chemical equation for the reaction and the starting concentrations or volumes of the reactants. You can then use stoichiometry to determine the amount of product that will be formed.
For example, if you have the reaction: A + B → C + D, and you know the initial concentrations of A and B, you can use the stoichiometry of the reaction to calculate the change in concentration of C and D. Dividing this change by the volume of the solution gives you the molarity of the products.
4. Pressure can indeed affect reaction rates, but the relationship between them depends on the specific reaction and conditions.
For gaseous reactions, increasing the pressure can increase the reaction rate. This is because higher pressure leads to a higher concentration of gas particles, which results in more frequent collisions between the reactant molecules. More collisions increase the chances of successful reactions, thus accelerating the reaction rate. However, this relationship is not applicable to all reactions, especially those that involve solids or liquids.
6. The statement that reaction rate decreases as pressure increases is not necessarily true. As mentioned earlier, the effect of pressure on reaction rate depends on the specific reaction and conditions. While increasing pressure can decrease the reaction rate in some cases, it can also increase the rate in others. Therefore, it is incorrect to make a general statement that applies to all reactions.
