NH4Cl(s) → NH3(g) + HCl(g) ∆H0=176 kJ/mol ∆S0=0.285 kJ/(mol K) What can be deduced from to this reaction?

At room temperature, the reaction is not spontaneous. However, at high temperatures, like 800 °C, the free energy value turns negative and this reaction becomes spontaneous.

At room temperature, the reaction is spontaneous. If the temperature is increased, the free energy value turns negative and the reaction stays spontaneous.

At room temperature, the reaction is spontaneous. However, at high temperatures, like 800 °C, the free energy value turns negative and this reaction becomes nonspontaneous.

At room temperature the reaction is not spontaneous. However, at lower temperatures, like –40 °C, the free energy value turns negative and this reaction becomes spontaneous.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
