Question

The initial rate of zero order reaction of the gaseous reaction A(g) $\to$ 2B(g) is ${10}^{-2}$ M/min. If the initial concentration of A is 0.1 M, what would be the concentration of B after 60 sec?

• A. 0.09 M
• B. 0.01 M
• C. 0.02 M
• D. 0.002 M

Answer 1

The correct option is C 0.02 M

$\frac{0.1-[A{]}_f}{1}={10}^{-2}[A{]}_f=0.1-0.01[B]=2\times 0.01=0.02M$
