Homework Answers
A+ B + heat = C + D
e.
if we cool the system, since this is endothermic, the system shifts from products to reactants
f.
if we het the system, then there is enough energy to produce C and D. shift goes form left to right
Q3.
addition of NaOH will form OH- in solution, which reacts with H3O+ to form H2O
this shift goes form right to left.
the acid in ionic species, C2H3O2- decreases
