In part 2 of the lab, you discovered the relationship between temperature (T) and pressure (P) of a gas. Write a mathematical equation showing that pressure (P) divided by temperature (T) remains equal to a constant (k). Hint: Use the forward slash (/) for the divided-by sign and remember that capitalization matters!

It states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature. where P is the pressure, T is the absolute temperature, and k is another proportionality constant.

Explanation: Try that

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
