P Q is a zero order reaction. If the concentration of P decreases from 0.1 M to 0.05 in 10 seconds, the concentration of P after 15 seconds time is

Step-by-step solution

Given that, P Q is a zero order reaction. Initial concentration, [A]₀=0.1 M Final concentration, [A]_t=0.05 M Time taken, t=10 ~s For, zero order reaction, k= [A]₀-[A]_t t = 0.1-0.05 10 =0.005 M s ⁻¹ Now, for concentration of P after 15 seconds, 0.005= [0.05]-P 15 On solving we will get, P=0.025 M
