1.	For the system A2(g)+B2(g)⇌2AB(g), △H=+5 kJ/mole. If the activation energy for the forward step is 100 kcal/mole. If graph of ln(kb) vs T is drawn then find the value of the slope at 500 K. (kb = rate constant of the backward reaction, take 1 cal = 4.2 J and the gas constant R = 8.3 J/molK)
Answer» For the system $A_{2} (g) + B_{2} (g) ⇌ 2 A B (g), △ H = + 5 k J / m o l e .$ If the activation energy for the forward step is 100 kcal/mole. If graph of $l n (k_{b})$ vs T is drawn then find the value of the slope at 500 K. ( $k_{b}$ = rate constant of the backward reaction, take 1 cal = 4.2 J and the gas constant R = 8.3 J/molK)
