Given a heat source of 200c and a heat sink of 20c, what is the maximum theoretical efficiency for a carnot engine? (numerical percentage out of 100 without the % symbol)

Answer : The maximum theoretical efficiency for a Carnot engine is 90.

Explanation :

Efficiency of carnot heat engine : It is the ratio of work done by the system to the system to the amount of heat transferred to the system at the higher temperature.

Formula used :

where,

= efficiency of carnot engine = ?

= heat supplied by hot source = 200 C

= heat supplied by cold source  = 20 C

Now put all the given values in this formula, we get :

Therefore, the maximum theoretical efficiency for a Carnot engine is 90.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

increased stability in the completion of fluorine's outer shell.
