In a series of experiments on the first order decomposition of NOBr, rate constants were

Question

determined at two different temperatures. At 87 °C, the rate constant was 9.3×10-6 s-1 while
at 187 °C, the rate constant was 6.9×10-4 s-1. What is the rate constant at 187°C?

Answer 1

Is this the question you intended to post? Would you believe 6.9×10-4 s-1?
