An ideal gas initially at 600 k and 10 bar undergoes a four-step mechanically reversible cycle in a closed system .in step 12, pressure decreases isothermally to 3 bar, in step 23, pressure decreases at constant volume to 2 bar, in step 34, volume decreases at constant pressure; and in step 41 ,the gas returns adiabatically to the initial state. take cp=(7/2)r and cv=(5/2)r
(a) sketch the cycle in pv diagram.
(b) determine (where unknown) both t and p or state 1, 2, 3, and 4.
(c) calculate w, q, δu, and δh for each step of the cycle.

How do i complete this electrolysis of water lab? i’m at home, so i don’t have the materials, and the lab didn’t properly work and was incomplete at school.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
