A+ heat -> b endothermic reaction δh (+)

a -> b + heat exothermic reaction δh

if the heat is in the side of reactants of the reaction an increase of temperature will favor the formation of products and vice versa

"based on the reaction given above, as the temperature decreases, the formation of the reactants will:

decrease
increase
remained constant
indeterminate"

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
