Answer:
3.95 x 10³ s⁻¹.
Explanation:
∵ The value of the half-life is independent of the initial concentration of the reactant present.
∴ The reaction is a first order reaction.
- <em>The relation between half-life (t1/2) and rate constant for the first order reaction is: (t1/2) = ln2/k = 0.693/k.</em>
∴ k = ln2 / (t1/2) = 0.693 / (1.751 x 10⁻⁴ s) = 3.95 x 10³ s⁻¹.

LAw of conservation of Energy is an important concept to solve this problem. The energy released is equal to the energy absorbed.
Ice undergoes latent heat. MEaning there is a change in phase but not temperature and the energy is solved by (enthalpy of fusion)(mass) = 333.5J/g)(8.5g). =2834.75J.
This is equal to the energy released by the water. The energy is computed by (mass)(specific heat of water)(temperature change) = (255g)(4.16J/gK)(T)
Final equation is:
2834.75 = 255(4.16)(T)
T = 2.67K
