Determine the rate of a reaction that follows the rate law: rate = K[A] M[B]N, where:
k= 1.5
[A] = 1 M
[B] = 3 M
m= 2
n=1
O A. 1.5 (mol/L)/s
B. 9.0 (mol/L)/s
C. 4.5 (mol/L)/s
D. 13.5 (mol/L)/s

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
