Endothermic reaction is a type of reaction that absorbs energy during the process. the gauge for this reaction is the change in enthalpy which should be positive. This means the energy of the products should be greater than the energy of the reactants. The graph illustrates an uphill form.

I think the correct answer would be always parabolic. The reaction pathway graph for an endothermic reaction would always be parabolic where the products have higher energy than the reactants. Hope this answers the question.

What is the value of 1.5 ATM of gas at 20°C and a 3 L vessel are heated at 30°C at a pressure of 5.2 ATM
vampirchik [111]

Answer:

The answer will be approximately 1.0L

Explanation:

The problem has not been properly specified. You could have specified a gas in a PISTON, whose volume would decrease with increased pressure, and increase with increased temperature.

For such a system, we would use the  

combined gas law:

\frac{P1V1}{T1}=\frac{P2V2}{T2}

V_{2}= \frac{P1V1}{T1}\times\frac{T2}{P2}

                       =\frac{1.5\times3.0\times303}{293\times5.2}

                        \approx1.0L

PLEASE ANSWER
trapecia [35]

The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.

<u>Explanation:</u>

  • The reaction commences when the compounds on the reactant side are ready to react to give the product.  
  • The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.  
  • It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.  
  • In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
