The hydrolysis of sucrose (c12h22011) into glucose and fructose in acidic solution is a first-order reaction with a rate constant of 1.8 x 10-45-1 at 25°c. determine the mass (g) of sucrose that is consumed when 2.15 l of a 0.223 m sucrose solution is allowed to react for 282 minutes. enter your answer as an integer. previous next not saved submit qu.

Answer : The mass of sucrose consumed is 156.1 grams.

Explanation :

The expression for first order reaction is:

where,

= concentration of sucrose at time 't'

= concentration of sucrose at time '0' = 0.223 M

k = rate constant =

t = time = 282 min = 16920 s    (1 min = 60 s)

Now put all the given values in the above expression, we get:

Now we have to calculate the initial and final moles of sucrose.

Number of moles of sucrose hydrolysed =

Number of moles of sucrose hydrolysed =

Now we have to calculate the mass of sucrose used.

Therefore, the mass of sucrose consumed is 156.1 grams.
