GUJCET Chemistry Questions

Question 1:

1 Reaction 2A→B+3C is a zero-order reaction. What will be the rate of production for "C"?

Correct Answer: 10.5×10−4 mol L−1 s−1
View Solution

For the reaction \(2A \rightarrow B + 3C\), the rate of reaction is: Rate \( = -\frac{1}{2}\frac{d[A]}{dt} = \frac{d[B]}{dt} = \frac{1}{3}\frac{d[C]}{dt} \). Since it is a zero-order reaction, Rate \( = k \). Therefore, \(\frac{1}{3}\frac{d[C]}{dt} = k\) and \(\frac{d[C]}{dt} = 3k\). Given \(k = 3.5 \times 10^{-4} mol L^{-1} s^{-1}\), we have \(\frac{d[C]}{dt} = 3 \times (3.5 \times 10^{-4}) = 10.5 \times 10^{-4} mol L^{-1} s^{-1}\).
