Using your (Qheat) answer from the last problem calculate (C) the specific heat of the metal. The initial temperature of the metal is 100 C which cooled to a final
system temperature of 50 C when place in the water. The mass of the metal is 25
grams
8.36 J/g C
O 50 J/g°C
O 120 J/gºC
69.88 J/gºc

Hope you find the answer

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
