QNEET-2022-Ch-508: NEET 2022 Chemistry - Class 12 NEET-2022-Ch-508 Solution: For a chemical reaction \(4A + 3B 6C + 9D\) Rate of formation…

For a chemical reaction 4A+3B→6C+9D4A + 3B \rightarrow 6C + 9D Rate of formation of C is 6×10−2 mol L−1 s−16 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1} and rate of disappearance of A is 4×10−2 mol L−1 s−14 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1}. The rate of reaction and amount of B consumed in interval of 10 seconds respectively will be: 10×10−2 mol L−1 s−110 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1} and 30×10−2 mol L−130 \times 10^{-2}\ \text{mol L}^{-1} 1×10−2 mol L−1 s−11 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1} and 30×10−2 mol L−130 \times 10^{-2}\ \text{mol L}^{-1} 10×10−2 mol L−1 s−110 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1} and 10×10−2 mol L−110 \times 10^{-2}\ \text{mol L}^{-1} 1×10−2 mol L−1 s−11 \times 10^{-2}\ \text{mol L}^{-1}\ \text{s}^{-1} and 10×10−2 mol L−110 \times 10^{-2}\ \text{mol L}^{-1}
