When the pressure changes from 1417 psi to psi the volume changes from 0.145 l to 0.878 l and the temperature changes from 287 k to 196k

When the pressure changes from 1417 psi to  160.186 psi the volume changes from 0.145 L to 0.878 l and the temperature changes from 287 k to 196 k

Explanation:

According to general gas equation:

P₁V₁/T₁ = P₂V₂/T₂

Given data:

Initial volume = 0.145 L

Initial pressure = 1417 psi (1417/14.696 =96.42 atm)

Initial temperature = 287 K

Final temperature = 196 K

Final volume = 0.878 L

Final pressure = ?

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂  = Final temperature

Solution:

P₂ = P₁V₁ T₂/ T₁ V₂  

P₂ = 96.42 atm × 0.145 L × 196 K / 287 K × 0.878 L

P₂  =  2740.26 atm .L.  K  / 251.99 k. L

P₂  = 10.9 atm

atm to psi:

10.9 × 14.696 = 160.186 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.

the answer is 0.42 is that is an option. this question provides no info
