Question

in the following first order completing reactions. A+Reagent gives Product,,, B + Reagent gives Product. the ratio of K1/K2 if only 50% of B will have been reacted, when 94% of A has been reacted is- 1) 4.06 2) 0.2463) 2.064) 0.06

Answer 1

uestion 3.

Give the steps you will use to separate the variables and + 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 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

⇒ 3n + 3 = 48 ÷ 3
