Calculate the work done by the system when 2 moles of hydrogen gas is produced by the following reaction in a flask fitted with an inflatable balloon.
Zn(s) +2HCl(aq) = ZnCl₂(aq) + H₂(g)

Question

Calculate the work done by the system when 2 moles of hydrogen gas is produced by the following reaction in a flask fitted with an inflatable balloon. Zn(s)+2HCl(aq)= ZnCl₂(aq)+ H₂(g)

Quizplus · Accepted Answer

The reaction is an exothermic reaction, which means it releases energy in the form of heat. The production of hydrogen gas implies that the reaction is moving towards products, which means it is releasing energy. Therefore, the work done by the system is negative, indicating that the surroundings are doing work on the system. Hence, the correct answer is (B) -4.8 kJ.
