Enter your answer in the provided box. Remember to enter your answer to the correct number of significant figures. For the reaction: A(g) + B(g) → AB(g) the rate is 0.24 mol/L·s, when [A]0 = [B]0 = 1.0 mol/L. If the reaction is first order in B and second order in A, what is the rate when [A]0 = 2.6 mol/L and [B]0 = 2.7 mol/L?
Enter your answer in the provided box. Remember to enter your answer to the correct number of significant figures. For the following reaction, the rate is 0.27 mol/(L·s) when [A]0 = [B]0 = 1.0 mol/L: A(g) + B(g)→ AB(g) If the reaction is first order in B and second order in A, what is the rate when [A]0 = 2.0 mol/L and [B]0 = 3.3 mol/L?
