Question

In the following reaction A -> 2B + C, rate constant is 0.002 Ms-1. If we start with 2 M of A then conc. of B after completion of reaction is​

Answer 1

Unit of k indicates that it's a zero-order reaction.According to zero-order reaction.Rate of reaction=kRate of formation of B=time( in seconds)Concenteration of B=kConcentration of B after 10mins=kt=1.2×10−2×10×60=7.2M
