Which phrase best describes the following reaction...2H2O(l) + heat <--> 2H2(g) + O2(g)
Br2(s) --> Br2(g)
potential energy
temperature is decreased and pressure is increased
2H2(g) + O2(g) <--> 2H2O(g)
The equilibrium shifts to the right and concentration of HI increases
3
endothermic, absorbing energy
an exothermic reaction
The delta H of a chemical reaction refers to the change in
Br2(s) --> Br2(g)
potential energy
temperature is decreased and pressure is increased
2H2(g) + O2(g) <--> 2H2O(g)
The equilibrium shifts to the right and concentration of HI increases
3
endothermic, absorbing energy
