Q. The rate constant for a reaction with activation energy 50 kJ/mol at 300 K is 2.0 × 10⁻⁵ s⁻¹. At 310 K, the rate constant would be approximately:

300 K पर 50 kJ/mol सक्रियण ऊर्जा वाली प्रतिक्रिया के लिए दर स्थिरांक 2.0 × 10⁻⁵ s⁻¹ है। 310 K पर, दर स्थिरांक लगभग होगा:

2.0 × 10⁻⁵ s⁻¹
2.0 × 10⁻⁵ एस⁻¹

4.0 × 10⁻⁵ s⁻¹

5.5 × 10⁻⁵ s⁻¹

8.0 × 10⁻⁵ s⁻¹
8.0 × 10⁻⁵ एस⁻¹

Using Arrhenius approximation: doubling $k$ for a 10 K rise with 50 kJ/mol $E_a$ is common. Calculations give about $4.0 \times 10^{-6}$ .
