Answer:

(a).

order \: of \: A = 2 \\ order \: of \:B  = 0 \\ rate = k[A] {}^{2} [B]

(b)

0.32 \times  {10}^{ - 3}  = k {(0.12)}^{2} (0.15) \\ k = 0.148 \:  {mol}^{ - 2}  {dm}^{6}  {s}^{ - 1}

(c). The rate increases because kinetic energy of reactant molecules increases.

A calorimeter contains 500 g of water at 25°C.....

the temperature of the water inside the calorimeter is 39.4°C.....

The specific heat of water is 4.18 J/g-°C.

energy needed to heat the water = specific heat * mass * temp difference

= 4.18 J/g-°C * 500 g * (39.4°C - 25°C)

= 4.18*500*14.4

= 30096J

or approx. 30kJ
