In a chemical equilibrium, the rate constant for the backward reaction...
Understanding Chemical Equilibrium
In a chemical equilibrium, the relationship between the rate constants of the forward and backward reactions is defined by the equilibrium constant (K). The equilibrium constant is given by the ratio of the rate constants:
Equation for Equilibrium Constant
\[ K = \frac{k_{forward}}{k_{backward}} \]
Where:
- \( K \) is the equilibrium constant
- \( k_{forward} \) is the rate constant for the forward reaction
- \( k_{backward} \) is the rate constant for the backward reaction
Given Values
- \( k_{backward} = 7.5 \times 10^{-4} \)
- \( K = 1.5 \)
Calculating the Forward Rate Constant
To find the rate constant for the forward reaction, rearrange the equilibrium constant equation:
\[ k_{forward} = K \times k_{backward} \]
Substituting the given values:
\[ k_{forward} = 1.5 \times (7.5 \times 10^{-4}) \]
Performing the Calculation
- Calculate \( k_{forward} \):
\[ k_{forward} = 1.5 \times 7.5 = 11.25 \]
- Now multiply by \( 10^{-4} \):
\[ k_{forward} = 11.25 \times 10^{-4} = 1.125 \times 10^{-3} \]
Conclusion
The calculated rate constant for the forward reaction is approximately \( 1.12 \times 10^{-3} \).
Thus, the correct answer is **c) 1.12 x 10^-3**.
