The rate constant for the decomposition of a substance X is 6.2×10⁻³ s⁻¹. This reaction follows the first order kinetics. If the initial rate of decomposition of X is 3.1×10⁻⁴ Ms⁻¹, calculate the initial concentration of X. Also calculate the time required for 87% decomposition of X at ths temperature.
Time required for 87% decomposition of X=34 minutes
