A certain reaction is endothermic in the forward direction. The reaction has less moles of gas on the product side. Which of the following stresses would increase the yield of the products (shift right)?

Increasing the pressure

Decreasing the temperature

Increasing the volume

Decreasing the reactant concentration

answerlinnaeus;

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
