Straight line with zero slope
Straight sloping line
Hyperbola
Parabola
6)
How can we estimate the rate of the reaction between sodium thiosulphate and hydrochloric acid?
From the volume of HCl.
From the volume of distilled water.
From the amount of sulphur dioxide gas produced.
By measuring the time take for the forming a certain amount of sulphur.
7)
Consider the chemical reaction, Na₂S₂O₃ (aq) + 2HCl (l) → S (s) + 2NaCl (aq) + SO₂ (g) + H₂O (l). The rate of this reaction depends on the concentration of which of the following compound?
NaCl
H₂O
Na₂S₂O₃
SO₂
8)
Which one of the following represents the graph obtained by plotting 1/Time for the appearance of sulphur Vs Conc. of Na₂S₂O₃ obtained in the reaction between sodium thiosulphate and HCl?
