Which of the following changes will decrease the rate of collisions between gaseous molecules oftype a and b in a closed container?
a. decrease the volume of the container
b. increase the temperature of the system
c. add a molecules
d. take away b molecules
e. add an accelerating catalyst

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.

idk i’m struggling too

particle   p is an electron and particle q is a neutron
