An air-standard Otto cycle has a compression ratio of 9. At the beginning of compression, p1 = 95 kPa and T1 = 310 K. The mass of air is 3 g, and the maximum temperature in the cycle is 1020 K. Determine:
(a). the heat rejection, in kJ,
(b). the net work, in kJ,
(c). the thermal efficiency,
(d). the mean effective pressure, in kPa.

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
