For a certain chemical reaction variation in the concentration ln [R] vs. time plot is given alongside. For this reaction: 1. What is the order of the reaction? 2. What are the units of rate constant k? 3. Give the relationship between k and t1/2 (half-life period). 4. What is the slope of the curve? 5. Draw the plot log [R]0 /[R] vs time t(s).

1. First order. 2. Time-1 (s-1) 3. k=0.693 t_ 1/2 4. Slope = - k (rate constant). 5.

What type of deviation is shown by a mixture of ethanol and acetone? Give reason.
A solution of glucose (molar mass = 180 g mol^–1) in water is labelled as 10% (by mass). What would be the molality and molarity of the solution?

(Density of solution = 1.2 g mL^–1).
