Aheat engine absorbs 2500 j of heat from a hot reservoir and expels 1000 j to a cold reservoir. when it is run in reverse, with the same reservoirs, the engine pumps 2500 j of heat to the hot reservoir, requiring 1500 j of work to do so. find the ratio of the work done by the heat engine to the work done by the pump. is the heat engine reversible?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. 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 = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
