2SO2(g)+O2(g)⇌2SO3(g) is an exothermic reaction. What happens to the equilibrium if temperature increases?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the product of the pressure and volume is also constant

let that person have a turn to speak : )

the answer is na (sodium)
