Graph Plot these data that show how the mass of sulfur increases with an increase in volume.
Determine the density of sulfur from the slope
of the line.

The answer is 1.82 j/g°c                  

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b

The answer is:   [d]:   "ultraviolet" {"  uv  "} .

The heat added represents an energy change.
