The gas-phase decomposition of CH3CHO(g) occurs according to the equation CH3CHO(g) → CH4(g) + CO(g) and is second order. The value of the rate constant is 0.105 M–1s-1 at 490°C. If the concentration of CH3CHO(g) is 0.012 M initially, what will be its concentration 5.0 minutes later?

What happens when the temperature of a solution increases?
