**Title: Calculation of Steady-State Creep Rate**
**Description:**
This problem involves calculating the steady-state creep rate for some alloy under specified conditions. Creep is an important phenomenon observed in materials subjected to high levels of stress at elevated temperatures.
**Data Provided:**
- Steady-state creep rate data at 200°C (473 K) are given for some alloy.
- The activation energy for creep is known to be 150000 J/mol.
- You are to compute the steady-state creep rate at a temperature of 230°C.
**Table:**
The table provided shows the relationship between the steady state creep rate (\(\dot{\varepsilon_s}\)) and stress (\(\sigma\)):
| \(\dot{\varepsilon_s}\) (h\(^{-1}\)) | \(\sigma\) (MPa) |
|-------------------------------------|-----------------|
| \(2.4 \times 10^{-3}\) | 53 |
| \(2.7 \times 10^{-2}\) | 71 |
**Task:**
Using the known activation energy and the above data, compute the steady-state creep rate at a higher temperature of 230°C (503 K) and a stress level of 46.0 MPa.
