Question
The Arrhenius equation may be used to calculate the activation energy of a reaction. Which plot will generate a straight line with u slope of -E_a/R? k versus I/T k versus T l/k versus ln(T) In(k) versus ln(T) In(k) versus 1/T Which one of the following molecules will have the lowest boiling point? H_2O NaCl MgSO_4 Nil, CH_4 Which of the following units of concentration requires the use of a volumetric flask when preparing a solution? mole fraction molarity ppm (w/w) mass percent molality Which equation represents the number of atoms in a body-centered cubic unit cell? # atoms = - (6) + 1/8 (8) # atoms = 1/8(8) #atoms = 1 + 1/2(6) + 1/8(8) #atoms = 1/4 (8)Explanation / Answer
9 The graph ploted between lnK AND 1/T is a straight line. in this ln k is taken on y axis and 1/T is taken on x axis.
so the option is e
10. ammonia has lowest boiling point -33.340C SO THE OPTION D
11. molarity . so the option B is wright answer
12. bcc has two atom per unit cell . so the option is b
since bcc contains one at the centre and 8 atoms in the corners of the cube
