to temperature and activation energy. Catalysts: Lower activation energy, speeding up reactions without being consumed. Application: Catalysts are crucial in industrial processes, such as in catalytic converters or enzyme activity in biochemistry.
ce pressure is constant, use Charles's law form: \[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \] Step 4: Solve for \( V_2 \): \[ V_2 = V_1 \times \frac{T_2}{T_1} = 12.0 \times \frac{373}{293} \] \[ V_2 \approx 12.0 \times 1.272 \
