change in energy is expressed as + if energy is required and _ if it is released.

reactions wiht energy release happen without ant difficulty.

here the y to Z reaction requires the highest energy. so at equilibrium

Y- z is the slowest and goes on only when Y has accumilated sufficiently. so y will be highest at equilibrium.

ok?
