Question

Ammonia under a pressure of 15 atm at 27c is heated to 347c in a closed vessel in the presence of a catalyst. Under the conditions, nh3 is partially decomposed according to the equation,2nh3 n2+3h2.The vessel is such that the volume remains effectively constant where as pressure increases to 50 atm. Calculate the percentage of nh3 actually decomposed.

Answer 1

Answer:

Question 3.

Give the steps you will use to separate the variables and then solve the equation:

(a) 3n – 2 = 46

(b) 5m + 7 = 17

(c) 20p3=40

(d) 3p10=6

Solution:

(a) 3n – 2 = 46

⇒ 3n- 2 + 2 = 46+ 2 (adding 2 to both sides)

⇒ 3n = 48

⇒ 3n + 3 = 48 ÷ 3
