(58) the pressure of a gas in a tank is 422 psi at
20.0k. what is the pressure at 60.0k?
a. 1270 psi
7.480 atm
c. 1270 atm
d. 480 psi

1270 Psi

We are given;

We are required to determine the pressure at 60.0 K

Hence;

Therefore;

P₂=1266 Psi

   = 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
