What would the output of the following code be?

```python
import numpy as np
from chempy import balance_stoichiometry, Equilibrium

# Define the chemical reaction and its equilibrium constant
reaction = {'H2 + I2': '2 HI'}
Kc = 54.3

# Balance the stoichiometry of the reaction
reactants, products = balance_stoichiometry(*reaction.keys())

# Define the equilibrium
eq = Equilibrium(reaction, Kc)

# Calculate the equilibrium concentrations
conc0 = np.array([1.0, 1.0, 0.0])   # Initial concentrations of H2, I2, HI
conc = eq(conc0)

# Print the equilibrium concentrations
print('Equilibrium concentrations:')
for r, p, c in zip(reactants, products, conc):
    print('{}: {:.3f} M -> {}: {:.3f} M'.format(r, c, p, c))
```
