For the following zero order reaction, the half-life is 51.8 and the [A]0 = 1.42. Calculate the rate constant. 2 A → 3 B

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.

i think its 100

i hope this !
