Determine the rate law and the value of k for the following reaction using the data provided.
2 NO(g) + O2(g) > 2 NO2(g)
[NO]i (M) [O2]i (M) Initial Rate (M-1s-1)
0.030 0.0055 8.55 x 10^-3
0.030 0.0110 1.71 x 10^-2
0.060 0.0055 3.42 x 10^-2
Options:
A. Rate = 57 M-1s-1[NO][O2]
B. Rate = 3.8 M-1/2s-1[NO][O2]1/2
C. Rate = 3.1 x 10^5 M-3s-1[NO]2[O2]2
D. Rate = 1.7x10^3 M-2s–1[NO]2[O2]

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
