#' Effects of temperature on decomposition rates according to a linear model
#' 
#' Calculates the effects of temperature on decomposition rates according to a
#' linear model.
#' 
#' 
#' @param Temp A scalar or vector containing values of temperature for which
#' the effects on decomposition rates are calculated.
#' @param a A scalar defining the intercept of the linear function.
#' @param b A scalar defining the slope of the linear function.
#' @return A scalar or a vector containing the effects of temperature on
#' decomposition rates (unitless).
