The rate of a reaction doubles, when the temperature is changed from (300 ~K ) to (310 ~K ). Activation energy of the change is....... ( (R=8.314 ~J ~K ⁻¹ ~mol ⁻¹, 2=0.301 ) )
Options
- A(53.6 ~kJ ~mol ⁻¹ )
- B(48.6 ~kJ ~mol ⁻¹ )
- C(58.5 ~kJ ~mol ⁻¹ )
- D(60.5 ~kJ ~mol ⁻¹ )
Correct answer
A. (53.6 ~kJ ~mol ⁻¹ )
Step-by-step solution
From Arrhenius equation, ( aligned K₃₁₀ K₃₀₀ & = E_a 2.303 R ( 310-300 300 310 ) 2 & = E_a 2.303 8.314 10⁻³ ( 10 300 310 ) E_a & =53.6 ~kJ ~mol ⁻¹ aligned )
