True or False?

-for any process the enthalpy of the universe must increase or remain unchanged.

-and endothermic reaction results in heat being absorbed from the surroundings and a decrease in temperature of the surroundings.

Expert Solution

statement first [ for any process the enthalpy of the universe must increase or remain unchanged ] FALSE

as Enthalpy H so delta H can be either postive or negtive so it is not mandatory tfor enthalpy to always increase .

[ and endothermic reaction results in heat being absorbed from the surroundings and a decrease in temperature of the surroundings ] TRUE

as according to defination of endothermic reaction these reaction requires energy to proceed so resulting into heat withdrawal from sorrounding so that Tempreture of sorrounding decreses.

where exothermic reaction results into release of heat in sorrounding and rise in tempreature
