Question

The data provided in the table were obtained from the following reaction, carried out at 273 𝐾. 𝐴 + 𝐵 → 𝐶  Initial concentration of [𝐴] 𝑚𝑜𝑙 $𝐿 ^{−1}$ Initial concentration of [𝐵] 𝑚𝑜𝑙$𝐿 ^{−1}$ Initial rate of formation of [𝐶] 𝑚𝑜𝑙 $𝐿^{−1} 𝑠 ^{−1}$ 0.2 0.2 0.3 0.4 0.2 0.6 0.4 0.4 2.4 The order of the reaction with respect to 𝐴 is _________.

cdquestions Admin · Accepted Answer

To determine the order with respect to A, we compare the initial rates for the same concentration of [B]. The rate doubles as [A] doubles, indicating the order is 1 with respect to A
