In what time, the pressure of gas in the cylinder becomes 2 atm? — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Using the integrated rate law: ln[(P_t - 1)/19] = -kt → ln[(2 - 1)/19] = - (0.001/19) × t → ln(1/19) = -0.001/19 × t → 2.94 × 19 / 0.001 ≈ 55000 s. The key lists (a) 2900 s as correct.
